Multi-Axis Motion for Lithography Masking
Challenge
A leading supplier of laser processing equipment to the semiconductor industry wanted a next generation masking system for extreme UV lithography. The customer approached Steinmeyer with a demanding set of requirements. The motion system needed flexibility to provide fine adjustment during processing and coarse movement into a service position outside the optical path. Travel of 160mm was required in the horizontal axis and 50mm in the vertical axis, with speeds up to 50mm/sec and repeatability of better than 2 microns. The mask also needed to tilt as much as 1.5 degrees around the optical axis. Finally, the dry nitrogen atmosphere and strict boundaries on contamination levels made the choice of materials and lubricants challenging.
Steinmeyer Mechatronik, a division of Steinmeyer, designed an innovative multi-drive configuration. It features stainless steel, 12 x 5 preloaded ball screws. Two vertical drives enable both translation and tilt. A stage supporting both vertical drives moves the mask horizontally. The mask frame with the associated pivot points are magnetically preloaded, which enables easy service plus backlash-free tilt. Further, the motor encoder assembly is easily detachable for quick servicing.
Special design elements regarding coatings and ball screw lubricants were also incorporated to address demands unique to this application. An eUV absorbent coating was applied on all internal surfaces to minimize signal scattering. Also, a highly specialized lubricant was selected. This PFPE oil is chemically stable under eUV exposure while exhibiting extremely low outgassing. It is also thermally stable, nonflammable, and insoluble in water, acids, bases, and most organic solvents.

Motion Control – Linear Focus Actuator from Equipment Solutions!
Motion Control – Linear Focus Actuator
 |
Forestville, CA – The LFA-1205 Linear Focus Actuator is a high performance compact positioning system. It was specifically developed for optical applications requiring both high precision and high-speed positioning over a short to medium stroke. The LFA-1205 is well suited for optical focusing and other micropositioning applications such as scanning interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, bio-technology, semiconductor test equipment. Note that this motor is normally configured with an analog position feedback sensor and can be optionally equipped with a digital quadrature feedback element. The key to this products immense success is its novel tubular architecture. This arrangement provides a means to send the optical path directly through the middle of the motor. The moving optic attached to the motors ‘C-mount’ is not cantilevered and so has no torques. The LFA-1205 Linear Focus Actuator is directly compatible with the SCA814 Servo Controlled Amplifier.
- 12 Millimeter clear aperture
- 5 millimeters of linear motion
- <50 nanometer positioning repeatability
- Small Step Response of <1 millisecond
- Threaded lens mount 70 x 70 x 50 millimeters, 600 grams
By design, the LFA-1205 Linear Focus Actuator rotates approximately 0.1 degrees or 1.7 milliradians for every 1 millimeter of translation. Through manufacturing tolerances only there can be a small amount of pitch and roll motion that is induced during the intended translation. These small but real error sources are routinely characterized during the manufacturing process using our AC400 Digital Autocollimator to control product uniformity.

Motion Control – Precisely Measure Curvature and Angles with New Dual-axis Pitch and Roll Stages!
Motion Control – Dual-axis Pitch and Roll Stages!
 |
Van Nuys, CA – Motion Control – The precise measurements of angles and the curvature of objects are easily determined using two new Pitch and Roll stages just introduced by OES (Optimal Engineering Systems, Inc.). The PR100-45-01 (pictured) is driven by stepper motors and the PR100-45-02 is driven by brushless servo motors with quadrature incremental optical encoders.
The Pitch axis (lower stage) is a high precision goniometer stage which features preloaded cross roller guides and a high ratio worm drive for smooth motion over a range of travel of +/- 45 degrees. It has a typical accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees. Additionally, this axis has end-of-travel limit switches.
The 100 mm diameter Roll axis (upper stage) has a 180:1 gear ratio for smooth motion and has a precise pattern of threaded holes for fixtures or tooling. This axis has an accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees. The Roll axis has a Home signal for initialization. Each axis features a calibrated scale to visually display the angle. The maximum speed with stepper motors is 14 degrees/second and 45 degrees/second with servo motors. The knobs of the stepper motors can be replaced with optional optical encoders for position verification.
The resolution of the PR100-45-01 stepper motor driven duel-axis stage depends on the resolution of the step motor driver resolution or the optical encoder if a servo motor is used. A resolution of 0.001 degrees equivalent to 3.6 arc-sec can be achieved using a10 micro-steps per step stepper motor driver or an encoder with a resolution of 500 cycles per revolution.
The PR100-45-02 that features servo motors and optical quadrature encoders are used for very precise closed loop operation and greater speeds. The PR100-45-01 and -02 stages can be ordered plug-and-play with a fully a compatible multi-axis motion controller from OES.

Motion Control – Case Study: Precision Ground Ball Screw Drives Universal Pipetting Module!
Motion Control Case Study – Pipetting
COVID-19 Testing / Sampling Applications
Reaching New Levels of Speed, Lifetime, and Force Sensitivity
Woburn, MA –Motion Control Components Ball Screws – Case Study –
Situation:
In the area of automated laboratory equipment, servo-controlled pipetting modules are a key component of high-throughput systems. A major, global OEM had been using an off-the-shelf linear actuator to drive the pipette. This actuator had a limited range of capability in terms of speed, positioning accuracy, and force sensitivity. Although it met the minimum technical requirements and was cost-effective, engineers soon were asked to push performance to the next level.
Challenge:
The company decided to develop a next-generation system. Throughput was essential, as it wanted to target the largest hospitals and laboratories handling tens of thousands of samples annually. The pipetting module also needed to have enhanced flexibility to support a greater variety of operations. It should allow for a wider range of speeds and be highly accurate in both positioning and bottom-finding. Engineers were also tasked with achieving a 10-year lifetime with little or no maintenance. This high lifetime was critical because their business model included free field service. To meet these new requirements, the actuator would have to be redesigned. In particular, the bearing configuration did not support the required accuracy and sensitivity. The supplier was unwilling to modify its design. Company engineers realized that they would have to design a custom actuator.
Resolution:
They came to Steinmeyer for a precision ground ball screw. They knew that Steinmeyer had world-class quality and a very wide selection of miniature screw sizes. For this project, they were able to consider shaft diameters of 5mm or 6mm, with pitch down to 0.5mm! They selected a 6mm screw to meet the challenge. Company engineers conducted extensive performance testing on the first prototype quantities. They put the new module through an exhaustive regimen of motion, and measured positioning, force sensitivity, friction torque, motor current, and other parameters. They verified that their module design met all of the new performance requirements. The company has since achieved FDA approval for the new system and formally launched commercial sales.
Future Plans:
Noise minimization is important for laboratory equipment. The next generation pipetting module will look to ensure the quietest possible operation. The OEM will be evaluating our proprietary super-finishing process called optiSLITE. This technology removes the largest irregularities left over from thread grinding of the shaft. The resulting surface yields a noticeably smoother and quieter operation.

Motion Control – Custom Linear Mechanisms
Custom Linear Mechanisms from Steinmeyer …
Welcome to Where Precision Is. You Can Turn to Steinmeyer for Design and Assembly of Custom Linear Mechanisms for your Precision Positioning Systems
Modern mechatronic systems consist of numerous precision components that must be assembled in complex configurations.

Our engineers can implement your finished design or optimize your concept.
For Example …
Linear Stage with Foldback Drive
Drive relocated to the rear
The task of this customer-specific OEM development was to create a travel path of 150 mm in 250 mm installation space, in which the load is wider than long. The available installation space had to be completely filled with an aluminum base body in order to achieve the necessary rigidity.
Integrated ball screw with synchronous belt
The ball screw was integrated between the base body and the moving carriage plate. It was also moved downwards via a pair of synchronized pulleys with synchronous belts. The transmission error of this additional transmission element could be minimized by optimally adjusting the pre-stress, thereby resulting in only a slight increase in repeatability errors. A compromise also had to be reached on the guiding system with regard to the guiding relationship. The lateral distance between the carriages had to be greater than the distance between the carriages in the direction of travel. Less stringent requirements for straightness made that acceptable.

For Example …
Zoom Unit
Sliding axes for the adjustment of two optics
Two lenses must be positioned relative to each other and also positioned together. Since the unit is exposed to stray radiation from the exposure process, lubrication must withstand these conditions in the long term. The basic solution consists of two sliding axes on a common guide system. Two moving sliding carriages have three carriages each, which allows them to move partially within each other in order to bring the lenses together as closely as possible. The drives consist of smoothened ball screw drives driven by a direct current motor with a rotary encoder. The motor encoder assembly is designed to be interchangeable for easy maintenance.
Designed for extremely dry environments
By choosing a PFPE-based lubricant and a special surface coating, the requirements for clean room compatibility and UV resistance were met. All accuracy-relevant parameters are verified by a measuring station after installation. This measuring station is located in the clean room and records accuracy, repeat accuracy, straightness, evenness and current consumption. Additional tests are performed to ensure minimum clearance in the bearing and smooth running of the drive system.

Voice Coil Positioning Stages – Overview –
The Voice Coil Positioning Stage is a compact, small footprint positioning stage. It is ideal for closed loop positioning applications with a short stroke where intricate position, velocity, and acceleration control is necessary.
Their compact size allows them to fit into small spaces. They have very low electrical and mechanical time constants. The low moving mass allows for high accelerations of light payloads.
The ironless core coil assembly has no magnetic attractive force to the stationary magnet assembly, which reduces the load on the bearing system, which increases the life of the bearing. There are no magnetic drag forces (hysteresis), which allows for higher accelerations.
These actuators are wound in such a way that no commutation is required for motion to occur. Electrical devices such as Hall Effects are not necessary. The result is a much simpler and more reliable system.
The VCS positioning stage incorporates the latest in linear motion technology:
Motors: non-commutated moving coil (NCC) or moving magnet (NCM) voice coil motors.
Bearings: Linear guidance and stiffness is achieved by using high precision ball slides or cross roller slides. Other types of bearings and bushings are available depending on the application.
Feedback: Non-contact optical or magnetic linear encoders with a center reference mark for homing. Typical encoder output is A and B square wave signals but sinusoidal output is available as an option. Analog feedback is available via LVDT or Force Transducer.
Limit Switches: Soft limits are typically used and monitored by the controller. But, if needed, end of travel limit switches may be included at both ends of the stroke. The switches can be either active high/low (5V to 24V). The limit switches can be used to shut down the amplifier or to signal the controller that an error has occurred. The limit switches can be an integral part of the encoder or can be mounted separately if required.
Hard Stops: Hard stops are incorporated into the ends of the stage to prevent over travel damage in the event of servo system failure.
Advantages:
- Small Size, High Force to Weight Ratio
- High Accelerations
- No Cogging or Commutation
- Custom Designs with Quick Turnaround Times
- High Flux Density Neodymium Magnets are Used
- Low Cost Economical Solution
Applications:
- Mirror Tilt and Focusing
- Z Axis for Pick and Place Equipment
- Medical Diagnostic Probes and Laser Beam Steering
- Vision Inspection
- Miniature Position Control
- Clean room
Stages can be ordered for any stroke up to 2 inches and any continuous force up to 100 lbs. The stages are built as the orders are placed, they are not stocked, as each customer requirement is different.
It should be noted that for both types of actuators (NCC & NCM) used for these stages, longer strokes are available but the efficiency or motor constant (Km) decreases as the stroke increases. This is due to the fact that the motor constant is inversely proportional to the stroke. If higher efficiency is desired for longer stroke actuators, the coil assembly can be wound as a multiphase coil and then it will have to be commutated. Please consult the factory for long stroke applications.

Motion Control – Custom Linear Mechanisms …
Welcome to Where Precision Is. You Can Turn to Steinmeyer for Design and Assembly of Custom Linear Mechanisms for your Precision Positioning Systems
Modern mechatronic systems consist of numerous precision components that must be assembled in complex configurations.

Our engineers can implement your finished design or optimize your concept.
Motorized Aperture Stage
Highest precision and compact design
The aperture control is used to adjust a pass-through window for a power laser and makes it possible to confine a laser beam to any rectangular format. The pass-through window is formed by means of four individual apertures, which are positioned by two drives. The height and width of the window can be adjusted almost infinitely from fully closed up to a size of 25 x 25 mm (maximum open); the smallest adjustment step is 50 nm. The beam center is fixed and cannot be changed.
Driven by DC motor and precision spindle with belt deflection
Since the pairs of individual apertures must be moved synchronously to adjust the pass-through window, two individual apertures each are moved by one spindle. The aperture control is driven by a DC motor and a precision spindle with belt deflection – a design with advantages: Owing to right-hand and left-hand threads on one spindle, two counter-rotating movements can be generated with one motor. In addition, the flat design requires only a short installation length in the optical beam path. Since the pairs of individual apertures must be moved synchronously to adjust the pass-through window, two individual apertures each are moved by one spindle. In this process, the parallelism of the apertures that are arranged on opposite sides deviates only by a maximum of 10 µm.
