SiGe Wet Process R&D Engineer — 28nm Integration

118-WW TMG MFG OPS; Lehi (UT); On-site; USD 120,000 - 180,000; Full time

Job summary

Texas Instruments in Lehi, Utah, is seeking a Wet Process Development Engineer to own the development, integration and qualification of wet etch and clean modules for 28nm SiGe and silicidation flows. You will drive chemistry formulation, tool integration, yield analysis and production readiness across the full device fabrication sequence.

You will partner with Epi, Lithography, Spacer Films and CMP teams, apply SEM/TEM/ellipsometry/AFM metrology, and lead multiple workstreams under schedule

Qualifications

• Master's or Ph.D. in Materials Science, Chemical Engineering, Electrical Engineering, Physics, or related field.
• 5+ years in R&D semiconductor wafer fabrication for advanced nodes (28nm or below).
• Hands-on experience with wet etch chemistries and with single-wafer or batch wet process tools.
• Ability to lead cross-functional teams from concept to production-ready status.

Responsibilities

• Module Integration: Develop and optimize wet process flows for SiGe epi-layer cleaning and selective removal without damage to underlying Si or gate oxide.
• Selective Etching: Define chemistries for high-precision isotropic and anisotropic etching with focus on SiGe/Si/silicided film selectivity and undercut control at 28nm geometries.
• Yield & Defectivity: Identify root causes of process-related defects using FMEA and 8D methodologies; implement SPC to support the yield ramp toward high-volume manufacturing.
• Cross-Functional Collaboration: Partner with Epi, Lithography, Spacer Films, and CMP teams to ensure seamless integration of wet modules into the full 28nm SiGe and silicidation fabrication flow.
• Metrology & Characterization: Utilize SEM, TEM, ellipsometry, and AFM to characterize surface roughness and etch profiles at atomic resolution.
