ASML US brings 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, the 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. Having joined the ASML family in 2016, HMI has become an integral part of our holistic lithography portfolio with innovative e-beam inspections solutions.

Job Description

-Makeconceptual design of the electron optics system according to systemperformance requirement.

-Simulatethe electron optical performance of the electron optics system, modify andfinalize the conceptual design, and define requirements toward electronicmodules which support the electron optics system.

-Make mechanical design of the electron optics systembased on the simulation result.

-Assemble and test the electron opticssub-modules, and integrate the sub-modules to make the electron opticssystem.

-Perform basic performance testing onthe test bench and make test reports.

-Integrate the electron optics system ontothe system platform. Test and verify the control functions of the electronicand software.

-Characterize the electron optics system’s resolution,current, distortion, and other optical characteristics on the systemplatform.

-Carryout electron optics experiments on the platform, analyze the test data, anddevelop solutions to optimize the performance of the electron optics system.Diagnose complex subsystem issues across algorithms, software,electronics, mechanics, vacuum and electron optics.

-Provideinput to new electron optics system specifications, system error budget,interfaces and working parameters for the optimum hardware/softwaresolution.

-Providetechnical support to the application engineers in developing applications,live demonstration and result analysis.
