Failure analysis strategies for multi-stacked memory devices with TSV interconnects
Failure analysis strategies for multi-stacked memory devices with TSV interconnects
Tuesday, November 3, 2015: 3:45 PM
Meeting Room D139 & 140 (Oregon Convention Center )
Summary:
In this paper we will demonstrate new approaches for failure diagnostics of DRAM Memory devices with stacked TSV structures. Especially defect localization by Lock-in-Thermography (LIT) and adapted preparation strategies for TSV sidewall shorts will be discussed. Five times stacked TSV daisy chain samples will be used with different TSV specific electrical failure modes.
