Principal Epi R&D Engineer

Coherent • Easton, PA

80d

About The Position

The position involves leading the development and optimization of SiC epitaxial growth processes, focusing on thickness and doping uniformity, as well as defect reduction through process tuning. The role requires driving continuous improvement initiatives across epitaxy platforms and leading R&D projects, including internal qualification efforts and facilitating seamless process transfer from R&D to production. Collaboration with substrate and epitaxy teams is essential to establish correlations and enhance Epi quality. The candidate will also interface with external vendors to identify and implement solutions aligned with product timelines and performance goals. Additionally, the role includes preparing technical reports and presentations, contributing to external publications, and participating in conferences.

Requirements

• PhD degree in Materials Science, Electrical Engineering, Physics, or related field.
• 3+ years of hands-on experience in SiC epitaxy, preferably in a semiconductor manufacturing or R&D environment.
• Deep understanding of crystal defects and strategies for control in SiC epitaxy.
• Experience with Epi reactor design and considerations.
• Strong understanding of CVD reactor operations and epitaxial growth mechanisms.
• Familiarity with process modeling and simulation tools.
• Experience with statistical data analysis and design of experiments.
• Knowledge of scientific principles and characterization techniques such as C-V, optical characterization, x-ray characterization, thickness, doping, roughness, etc.
• U.S. Citizenship, Permanent Resident Alien, or Protected Individual status due to ITAR compliance.
