  • Introduction

ASML is one of the world’s leading manufacturers of lithography systems that help enable Moore’s Law and the creation of increasingly powerful and capable electronic devices. Our San Diego-based light source division, Cymer, is renowned for developing both deep ultraviolet (DUV) lithography light sources and next generation extreme ultraviolet (EUV) light sources.As the world’s leading semiconductor equipment manufacturer, ASML enables chipmakers to produce cheaper, speedier chips – and to produce them faster – thereby enabling all the technology you use today. The systems we produce integrate several large and sophisticated machines, themselves each a feat of engineering innovation, precision, and speed.

We are a multinational company with over 70 locations in 16 countries, headquartered in Veldhoven, the Netherlands. We have 18 office locations around the United States including main offices in Wilton, CT, Chandler, AZ, San Jose, CA and San Diego, CA (EUV laser source creation).

In the Cymer Light Source (CLS) division in San Diego, we design and manufacture Deep Ultraviolet (DUV) lasers, used directly in the chipmaking process. Far from a basic “consumer” laser, these machines are complex, powerful, and flexible. The lasers we make require: durable and high-speed precise motion-controlled optics to maintain wavelength to femtometer accuracy under high laser powers; advanced materials to endure the harsh Fluorine-rich environments and high powers; clever mechanical designs to allow high performance and fit all the parts within a confined space, but still allow easy manufacturing and servicing.

If you have a passion for technology and innovation you’ll want to check us out. Be a part of progress.

One Company, One Goal, Limitless Innovation. It's our people that make the difference.

Job Mission

As a Controls Engineer at Cymer Light Source, you will be responsible for developing and improving critical controllers and other algorithms for the Deep Ultraviolet (DUV) lasers used in the manufacture of microchips, to enhance performance, increase reliability, and increase automation (lower cost). You will work on systems involving excimer lasers and their optical features (such as energy, wavelength, and spectral bandwidth), high-speed mechatronics, gas properties and handling, and ultra-precise signal timing. You will need to consider system modeling and physics, signal properties (noise, filtering, frequency content), actuator and sensor behaviors and limitations, nonlinear coupled and time-varying plant dynamics, and very large data sets. You will use a range of techniques and methodologies starting with classical and modern feedback control methods, and including advanced controls, signal processing, estimation, optimization, frequency-domain analysis, stochastics, data science, and clear logical thinking.

You will collaborate with systems engineers, software and firmware developers, electrical engineers, hardware designers, Marketing, and project management to develop concepts, perform engineering analysis and design, build and test prototypes, generate detailed requirements, and guide the final algorithms through implementation, into testing, and out to field production.

Solving these challenges requires expertise in system engineering, optics, physics, controls, mechanical engineering, electrical engineering, test engineering, embedded software and firmware, manufacturing, industrialization, and more. If you like extreme challenges, and passion for technology and innovation, and want to help bring the next generation of technology to the world, then come join ASML.

Job Description

The Cymer Light Source team in San Diego operates in a fast-paced, innovative, and challenging environment to develop DUV lasers and support technologies to enable both current and future lithography generations.
