01Project overview
Application context
Illustrative lithography positioning environment with defined integration requirements.
Challenge
Stabilize positioning while supporting the intended process workflow.
Solution concept
A coordinated platform integrating motion, sensing, and process interfaces.
Technologies considered
Precision axes, feedback, controls, vision, and application tooling.
Validation focus
Accuracy, repeatability, process consistency, and operating conditions.
02The challenge
- Motion cycles can constrain process throughput.
- Manual operations can introduce process variation.
- Accuracy targets need to be defined with the measurement method.
- Environment and interfaces influence the architecture.
03The solution concept
- Structured multi-axis architecture around the process.
- Feedback and controls considered together.
- Tooling and sensing integrated into the motion workflow.
- Validation criteria agreed before implementation.
