Full Job Description
What You'll Be Doing
Coordinate with device designers to develop the epitaxial growth recipes needed for the devices to meet the wide range of performance requirements including output power, drive voltage, beam characteristics, wavelength, high-speed operation and reliability
EPI design includes, but is not limited to, modeling design inputs such as layer thicknesses and compositions, doping profiles, active regions, growth conditions to outputs such as mode profiles, beam divergence and electrical resistance.
EPI designs must align with the wafer processing and device design technology with high yield
Translate designs into EPI growth recipes and interact with internal EPI growers or manage external vendors to execute the growths
For each growth campaign review all available calibration and EPI characterization data and feedback to internal or external growers or modify EPI designs as needed
Work with device designers and wafer process integration teams to launch process runs. Support NPI team to analyze all critical wafer processing, device testing and reliability data to feedback to EPI design improvements
Coordinate any special EPI related analysis to understand performance and reliability such as SIMS, TEM, EDX
Generate key intellectual property (IP) for novel ideas in device design or EPI designs
