Paper Abstract

Burn-in is crucial for ICs, especially for DRAM. To meet the target failure rate after releasing the products to customers, the manufacturers have to burn-in the chips after assembly and FT for a certain period of time to weed-out the weaker parts. It is important to determine the burn-in time and to set-up a re-burn-in strategy to meet required failure rate and to maintain cost-effective at the same time. This paper introduces an innovative approach to achieve these two objectives along with some practical concerns on burn-in at field applications. The proposed methodology can be applied on versatile statistical distributions. In this presentation, the selected failure mechanisms follows Weibull distribution to illustrate our approaches.
