ASML US, including its affiliates and subsidiaries, bring together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips. We design, develop, integrate, market and service these advanced machines, which enable our customers - the world’s leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics. Our headquarters are in Veldhoven, Netherlands and we have 18 office locations around the United States including main offices in Chandler, Arizona, San Jose and San Diego, California, Wilton, Connecticut, and Hillsboro, Oregon.

Job Mission

ASML is seeking an experienced Contamination Control Engineer to develop glass and ceramics manufacturing process to produce ultra-high precision systems. This person will join the Advanced Development Center in Wilton, Connecticut - A Research and Development team focused on proto-typing of next generation wafer/reticle clamping systems. The main job function is to investigate the current contamination control process and diagnostics, extend/improve capability and develop new solutions to solve challenging engineering problems associated with achieving nanometer scale precision.

This position may require access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. § 730, et seq.). As a condition of employment, qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require the Company to proceed with candidates who are immediately eligible to access controlled technology.

Job Description

The main focus of this position will be:

  • Understand particle and molecular contaminants transport mechanism in product and test equipment
  • Characterize type and amount of contamination by collecting contamination samples and performing relevant tests
  • Develop/identify cleaning methods by using proper materials, equipment and processes without sacrificing product performance
  • Develop methods to determine the degree of cleanliness and validate cleaning efficacy
  • Implement contamination budgeting and monitoring throughout the process
  • Write contamination control procedure and train technicians to efficiently implement the procedure in manufacturing
  • Create and maintain roadmap of cleaning technologies to support ASML products by investigating possible candidate techniques and evaluating their capabilities/limitations
  • Investigate material issues/challenges using appropriate material diagnostic tools (e.g. SEM , AFM, WLI, etc.)
  • Clearly communicate progress and status of ongoing technical activities to senior management
  • Support preparation of design reviews for the development team
  • Prepare engineer documentation (e.g. Element Performance Specifications, Element Design Specifications, Test Performance Specification, Test Analysis Reports, etc.) and release the documents by following change control process
  • Write engineering procedures and train technicians to efficiently transfer the build/alignment/test process to manufacturing
  • Support image analysis on data and derive conclusions
  • Some travel (~ 10%) to Europe, Asia and within the US can be expected
