... process improvement comes from two sources. (a) Knowing the defect is in the cell, any de-layering can go straight to the metal layer where the cell interconnects are routed, without the need to investigate any higher metal layer, and (b) having failure analysis investigate fewer layers reduces the...

... Abstract Failure analysis of steel welds may be divided into three categories. They include failures due to design deficiencies, weld-related defects usually found during inspection, and failures in field service. This chapter emphasizes the failures due to various discontinuities in the steel...
