Job Description

We are seeking a skilled Process Engineer to drive the optimization, stability, and continuous improvement of our Diffusion and Epitaxy (DIFF/EPI) operations. In this role, you will own the technical integrity of wafer fabrication processes, serving as the primary point of accountability for process health, yield optimization, and equipment performance.

You will act as a key technical resource, collaborating cross-functionally to troubleshoot complex issues, execute process characterization, and lead projects that enhance manufacturing capability. This position requires a balance of hands-on technical execution and analytical problem-solving to consistently meet our stringent quality and throughput targets.

Key Responsibilities:

* Take ownership of assigned processes, setting the direction for improvement, sustaining performance, and overall operational excellence.

* Partner closely with process and integration engineers to improve key process metrics-including SPC, yield, parametrics, and defects-and to achieve first-pass success on technology transfers.

* Lead the selection and qualification of semiconductor processing tools.

* Monitor fab performance metrics using statistical process control (SPC).

* Conduct root cause investigations of discrepant material and implement yield and defect improvement projects.

* Develop operating specifications and provide technical training to wafer fab personnel.

* Collaborate with equipment engineering to improve uptime, tool utilization, and process flexibility.

* Troubleshoot process and tool excursions to minimize impact on production.

* Identify cost savings opportunities and lead initiatives to reduce overall operating costs.

* Implement advanced process control methods to improve Cpk at critical process levels.

* Ensure proper matching and qualification of newly installed equipment to support production ramp.

* Develop new semiconductor manufacturing processes using design of experiments (DOE) methodology.

* Strengthen fault detection and classification (FDC) strategies within your areas of responsibility.
