Defect Reduction Metrology Engineer - Mocvd

We are seeking a skilled Defect Reduction Metrology Engineer with expertise in image-based

defect detection and classification to support our GaN MOCVD EPI manufacturing and ongoing

development activities. The ideal candidate will have a strong background in python, machine

learning and Candela Surface Defect Inspection Systems. This position is based at the company

headquarters in Goleta, CA and will be full-time/on-site for our production support.

Job Responsibilities:

This position will work with senior technical staff to improve current metrology and develop new processes for MOCVD wafer characterization and analysis. Their responsiblities will include:

● Develop image-based defect classification to accurately classify optical defects in semiconductors using python and machine learning.

● Track and establish possible correlation between substrate defects and epitaxial defects; calculate wafer usable area and die yields.

● Screen incoming substrates based on correlated epitaxy defects and calculate usable wafer area and die yields.

● Support statistical process control (SPC), continuous improvement efforts and the management and dissemination of metrology data in support of our GaN EPI manufacturing and ongoing development activities.

● Participate in a team effort to improve quality and performance of epi wafers; help generate new ideas and approaches.

● Summarize and present experimental findings in written reports and regular team meetings.

● Communicate and help to resolve technical and operational issues in a timely manner.
