Introduction to the job

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.

This position may require access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. § 730, et seq.). 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

Role and responsibilities

The Senior Optical Sensing Engineer will be responsible for the development of one or more metrology subsystems that measure and control the production of light in the extreme ultraviolet (EUV) source for next generation photolithography tools. These metrology systems use a variety of optical and electronic measurement techniques to accomplish their function. The engineer will provide specifications and technical guidance to the team of design engineer throughout the product development cycle. Engineering tasks will include design, development, testing, troubleshooting, and productization of the metrology subsystem(s). In addition, the engineer will provide technical leadership to the project, our suppliers, as well as supporting our customers’ technical needs.

Duties and Responsibilities:

  • Responsible for metrology definition and engineering design of one or more subsystems.
  • Leads the development and integration of innovative metrology system solutions to enable stable and efficient production of EUV for both research and product development.
  • Investigates the feasibility of applying scientific and mathematical design principles and concepts to potential inventions and products.
  • Plans and executes laboratory research pertaining to metrology design and validation in lab and cleanroom fabrication environment.
  • Develops specifications for optical and opto-mechanical modules in accordance with system requirements and cross-functional requirements.
  • Works with a cross-functional team to support the development, manufacturing, and integration of innovative core technologies into engineering solutions.
  • Communicates status reports, issues, and next steps across various functional disciplines.
  • Applies broad knowledge in optics, sensors, electronics, algorithms, software, and data analysis tools to drive metrology system improvements to enable continuously increased EUV power and system availability.
  • Leads and performs integration activities including troubleshooting the control system, developing and executing test plans, to ensure the system functions as designed in the EUV light source.
  • Leads the design and building of tools that allow debugging, analysis, and performance evaluation of metrology system performance.Leads the root cause analysis for metrology system failures in products for integration and fielded units during escalations.
  • Documents work results with system requirements, design specifications, procedures, and training materials.
  • Travel to supplier or customer sites to provide onsite support, including hands-on upgrade and troubleshooting in cleanroom fabrication facilities.
  • Performs other duties as assigned or required.

Education and experience

  • 0 years’ experience with a PhD.
  • 2+ years’ experience with a Master’s degree.
  • 4+ years’ experience with a Bachelor’s degree.
  • Ideal candidate usually possesses degree in optics, photonics, physics, biomedical engineering (with imaging focus), or imaging sciences.
  • Excellent written and verbal communication skills, capable of clearly explain technical issues and ideas to peers of other disciplines as well as management and customers.
  • Hands-on experience with optical alignment processes and tools, laser systems, and building signal detection and processing systems is required.
  • Experience with data analysis and visualization using advanced data analysis tools (e.g. MATLAB, Python) is required.
  • Experience with modeling optical and opto-mechanical systems using optical design and analysis software (e.g. Zemax) highly desirable.
  • Experience with mechanical design software e.g. NX is a plus.
  • Experience with supplier engagement is highly desirable.
  • Experience with semiconductor capital equipment industry is a plus.
  • Experience with advanced data acquisition and analysis tools (e.g. LabView) is a plus.
  • Able to propose and experimentally and/or theoretically validate innovative solutions to technical problems.
  • Able to convert an innovative idea into an engineering and practical solution.
  • Able to develop and review theoretical models and concepts.
  • Able to validate concepts through breadboard builds and analysis.
  • Proficient in MS Word, Excel, PowerPoint.
  • Experience with MS PROJECT and JIRA is a plus.
