Process Engineer –Deterministic Polishing & Lap Figure Control

Job Summary

ASML Wilton is seeking a Process Engineer to own deterministic polishing lap figure control across optical fabrication. The role is responsible for Continues Polishing (CP) Speed Polishing (PP) and spindle lap flatness standard conditioning methods and consistent polishing practices across platforms. The engineer will use process and metrology data to improve predictable polishing behavior First Pass Yield (FPY) and defect performance.

This is a technical ownership role focused on standardization qualification and sustained process control. The engineer will work with Manufacturing Metrology Quality Technology Equipment Engineering and other Process Engineers to implement universal polishing standards and close gaps affecting lap performance and process readiness.

This role requires a proactive engineering mindset: anticipating issues before they impact production driving structured 6P readiness performing thorough RCA and continuously evaluating new technologies and deterministic tools to strengthen long-term process control. This is not a reactive support role; the expectation is ownership foresight and continuous improvement.

Job Description

The role will establish measurable control requirements qualify standard methods reduce cross-platform variation and ensure improvements are documented and sustained.

Primary Responsibilities

Lap Flatness and Figure Control

Own CP PP and spindle lap flatness performance across Machining Generating Polishing (MGP).

Define lap flatness specifications control limits measurement methods and acceptance criteria.

Develop deterministic methods to monitor correct and maintain lap geometry.

Convert interferometry profilometry and process data into clear conditioning and process actions.

Conditioning Methods and Standardization

Develop qualify and maintain standard lap conditioning methods.

Define conditioner selection operating settings conditioning frequency and recovery methods.

Create and maintain universal standards for lap preparation conditioning monitoring and release.

Maintain work instructions specifications and standard work required for sustained method adoption.

Cross-Platform Process Consistency

Benchmark lap and polishing performance across CP PP and spindle platforms.

Identify and reduce machine-to-machine product-to-product and shift-to-shift variation.

Establish common process requirements while documenting justified platform-specific differences.

Support transfer and deployment of proven methods across applicable MGP work centers.

Qualification Readiness and Continuous Improvement

Lead qualification of new conditioning methods lap materials measurement techniques and related process changes.

Drive structured root cause analysis for lap-related defects FPY loss figure instability and process variation.

Ensure corrective actions are verified documented implemented and sustained.

Own process readiness milestones and close assigned actions within committed dates.

Support technician and engineer training and qualification on approved polishing standards.
