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 pro...
