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.

Cymer is an independently operated business within the ASML group that develops, manufactures and services deep-ultraviolet (DUV) light sources. The product portfolio includes excimer lasers using argon fluoride (ArF) or krypton fluoride (KrF) gases to generate light in the deep-ultraviolet spectrum. These lasers generate the light that photolithography scanners use to image patterns on silicon wafers. The research, development and manufacturing of DUV light sources is centered in San Diego.

The Discharge Chamber is one of the core modules for DUV light sources, where the discharge plasma is generated to provide DUV light (193nm or 248nm). The development goals include extending chamber lifetime, improving energy efficiency and stability, reducing cost, etc. Achieving these goals requires extensive collaboration among plasma physics, material science, electrical engineering, mechanical engineering, chemical engineering, flow dynamics, and more. If you have a passion for technology and innovation, please join us to develop this complex and challenging DUV discharge plasma chamber!

Role and responsibilities

A Sr. Plasma and Laser Physics Engineer is the technical owner for the development of Cymer DUV laser discharge chambers: responsible for designing, validating and reviewing new features that improve chamber performance. The chamber scientist works in a cross-functional team with Program/Project Managers, Technical Marketing, and System Engineers to develop and productize new technologies that enhance chamber performance.

Duties and Responsibilities

  • Drives the development & integration of innovative core technology elements and/or system concepts to improve excimer laser chambers.
  • Applies knowledge and experience in engineering (electrical engineering or mechanical engineering) or physics (electromagnetics, flow dynamics, plasma physics or acoustics) to improve the performance and reliability of excimer laser chambers.
  • Validates concepts through model simulation, prototype builds, system level testing and analysis.
  • Independently investigates scientific and technical problems and challenges and evaluates and recommends solutions.
  • Interacts with customers, suppliers and peers, prepares and presents reports to management, as well as in internal meetings and conferences.
  • Assists management on technical aspects of external collaboration activities.
  • Prepares and revises technical documentation, including technical memos, specification documents and design validation reports.
