Overview
PDF is seeking a Sr. Optics Engineer in Electrical Beam Optics to drive the R&D, manufacturing, and delivery of state-of-art Electron Beam Inspection systems designed by PDF Solutions, eProbeTM, for use at 300mm semiconductor wafer fabs for use in yield ramp and manufacturing control. The Optics Engineer must be a highly motivated and a self-driven team player with strong communication skills and possess the drive to deliver quality results on time in a dynamic, multi-discipline, intensive and highly productive environment.
Responsibilities
Work closely with PDF internal engineering team towards delivery of electron beam columns for next generations of eProbe systems
Simulate existing column designs under their full space range of operation. Match simulations to experimental data, refine model parameters of the simulation, and refine models of ebeam source.
Use simulation to drive new modes of operating the column e.g. with added lenses and deflectors.
Design and simulation in 3-D packages for non-rotationally symmetric column elements such as Wien filters and high-precision energy filters
Hands-on work with on PDF's Ebeam tool for column characterization
Qualifications
Masters/PhD in Electrical engineering, physics, material science, or similar engineering field
Strong experience in e-beam optics simulation preferably with Munro's code
Experience in any scripting or programming language (e.g. Python, Java, C#, C++)
Experience with any data analysis package (e.g. Excel, MATLAB, R, JMP)
Good analytical and engineering skills
Good written and verbal communication skills
Other desirable Skills and Experience
Experience or familiarity with 300mm semiconductor IC manufacturing
Experience or familiarity with semiconductor capital equipment, especially ebeam and ultra-high vacuum equipment.
Experience specific to ebeam 'inspection' columns and, even more so, in 'voltage contrast inspection' column is very desirable.
Hand-on experience in bringing up new ebeam columns, ebeam guns, ebeam electronics and ebeam test fixtures for characterization.
Pay Range
USD $150,000.00 - USD $200,000.00 /Yr.
