An experienced researcher in the area of compound semiconductor responsible for development of new and innovative epitaxy design in GaN on Silicon process technology to achieve best in class linearity and power added efficiency HEMT devices for PA design. The candidate will be responsible for collaboration with foundry and academic partners, devising new process flow using TCAD tools, design and layout of appropriate test structures, and testchip tape out to candidate fabs. The candidate will also be responsible for characterization and measurement of the testchip to verify the targeted performance improvement and publish report and present the result to the team. Upon achieving the performance target the candidate will be responsible for developing a compact model and implements it in PDK for design team to use for design of final product. The candidate will work closely with the design team to achieve the final product tape out.
