Senior Product Engineer - MOSFET Foundry Transfer & Yield Sustaining

The main focus is to support front-end technology transfer and the respective derivative products which includes, wafer-level data review, wafer sort/yield analysis, parametric trend monitoring, and wafer yield improvement. The role also coordinates downstream assembly, final test, characterization, reliability qualification, and manufacturing release transfer activities.

Job Location:

The ideal candidate will be working near one of our Vishay offices in Taipei, Taiwan Newport, UK, Binan, Philippines.

What you will be doing:

Foundry Transfer

• Coordinate with respective backend NPI engineering teams the processing of technology-transfer lots from wafer fabrication out through wafer sort, characterization, qualification, and safe launch
• Work with Fab Process Engineering and Process Integration to review process transfer status, risks, and action items.
• Drive lot track schedules, milestones, and issues; communicate risks to the Technology Transfer Project Lead and Product Engineering Director.

Wafer Yield & Data Analysis

• Review wafer sort data, wafer maps, WAT/PCM data, electrical yield, and parametric distributions.
• Identify process-related yield loss, electrical anomalies, and parametric shifts.
• Work with Fab Yield and Process Engineering teams on root-cause analysis, corrective actions, and yield improvement during safe launch through to product maturity.

Product Release Coordination - Probe, Characterization, Reliability Testing

• Project coordinates the following key activities in the product transfer cycle
• Wafer probe and engineering characterization activities before package assembly.
• DC and AC characterization within the characterization team and support correlation between wafer probe, final test, and reliability data.
• Assembly, Final Test, Reliability, Failure Analysis, Quality, Operations, and Supply Chain to support product release.
• Interface with reliability teams for AEC-Q101 reliability tests such as HTRB, HTGB, Temperature Cycling, Power Cycling, HAST, THB, HTSL, Autoclave, and package qualification testing.
• Support failure analysis reviews when yield, qualification, or test issues occur.
• Prepare engineering build reports, yield summaries, qualification updates, and manufacturing readiness materials.

What you will bring along:

• BS or MS in Electrical Engineering, Materials Science, Physics, or related discipline.
• 5–10+ years of semiconductor Product Engineering front end experience.
• Experience with Power MOSFET technologies
• Knowledge of wafer fabrication and wafer sort.
• Project coordination of package assembly and test would be advantageous.
• Experience coordinating engineering lots through NPI and technology transfer.
• Understanding of electrical characterization, reliability qualification, and failure analysis.
• Experience supporting wafer foundries and OSAT partners.
• Extensive use of yield management software
• Knowledge of SPC, Cp/Cpk, DOE, yield analysis, and statistical methods.
• Strong project coordination and cross-functional communication skills.
• Automotive semiconductor experience preferred
