Job Description
Key Responsibilities
1.Own and maintain wafer probe (CP) test specifications, limits, and methodologies for MEMS microphone products across development and high-volume production.
2.Analyze wafer probe data using statistical methods to:
o Define and refine test limits and guardbands
o Monitor Cp/Cpk, distributions, and parametric drift
3.Monitor and manage:
o Wafer yield performance
o Identify abnormal wafer maps, outliers, and distribution shifts
o SBL (Statistical Bin Limits) and SYL (Statistical Yield Limits)
4.Work closely with foundry to:
o Review probe data and ensure test integrity
o Monitor daily production trends and address issues promptly
5.Support both New Product Introduction (NPI) and sustaining products:
o Analyze characterization data
o Define initial test limits and continuously refine based on production data
6.Maintain and support probe hardware and setup:
o Work with Cascade probers and Keysight B1500
o Ensure measu...
