Reliability Monitoring
Sample Selection Criteria for Periodic Reliability Testing：
Quarterly Reliability Testing
Quarterly reliability tests are conducted on the device process technology platforms across different chip manufacturing facilities.
Selection of the Highest Volume Product
The product with the highest production volume within the device process technology platform during the quarter is selected for the quarterly reliability testing.
Periodic Reliability Test Program for Device Process Technology Platforms (Phase 1 + Phase 2)
| Phase | Test Items | Test Conditions | Sample Size | Duration | Acceptance Criteria | Remarks |
|---|---|---|---|---|---|---|
| Phase1 | HTGB | T=Tjmax, Vg=Follow qualification condition | 77*1 | 168H | Static: Within datasheet specifications Dynamic: Follow platform IOS or MP criteria | Test for the first 10 batches • Static: 77 units/batch • Dynamic: 8 sets/batch |
| HTRB | T=Tjmax, Vd=Follow qualification condition | 77*1 | 168H | |||
| Dynamic Rdson(DHTOL) | Follow Qual. Condition or MP capability | 8set*1 | 168H | |||
