Job details:
Bachelor’s/Master’s/PhD in Electrical Engineering, Physics, Materials Science, or related field
3–10 years of experience in semiconductor ion implantation process.
Strong understanding of:
Ion-solid interactions (range, straggle, channeling)
Dopant diffusion and activation
Implant damage and annealing mechanisms
Roles and Responsibilities
- Develop and optimize ion implantation processes for CMOS, power devices (Si, SiC, GaN), and advanced nodes
- Define implant conditions: energy, dose, tilt, rotation, species selection
- Work on junction engineering, LDD/HDD implants, well formation, and threshold voltage tuning
- Perform process characterization using SIMS, SRP, sheet resistance, and junction depth analysis
- Optimize beam tuning parameters: beam current, uniformity, scan, and dose control
- Work on channeling control and damage engineering (pre-amorphization implants, tilt/rotation strategies)
- Develop and maintain implant recipes on tools such as Axcelis, Applied Materials, or equivalent
- Troubleshoot issues related to:
Dose non-uniformity
Beam instability
Charging damage
Particle contamination
- Collaborate with integration teams for annealing (RTA/spike) and activation optimization
- Drive SPC, yield improvement, and defect reduction initiatives
- Perform DOE, data analysis, and statistical modeling (JMP, Python, or equivalent)
- Support tool matching, qualification, and production ramp-up
