Wet Process Development Engineer

Develop and qualify wet etch and clean modules for 28nm SiGe and silicidation device flows, enabling ramp from chemistry formulation through module integration, yield analysis, and production readiness. Optimize selective etching and module integration to protect underlying silicon and gate oxide, drive defect root-cause and yield improvements using FMEA/8D and SPC, and collaborate with Epi, Lithography, Spacer Films, and CMP teams. Characterize etch profiles with SEM, TEM, ellipsometry, and AFM.
