This article demonstrates the strengths and limitations of electrical testing for locating defects that contribute to contact failures in DRAMs. It presents three case studies, the first of which involves a write problem to a pair of cells that share

Weak open contacts are common in DRAM cell arrays where they act as a resistance between the cell capacitor and wordline transistor. This article discusses the role of weak open contacts in DRAM failures, the factors that influence their effect on re

Soft defect localization (SDL) is a method of laser scanning microscopy that utilizes the changing pass/fail behavior of an integrated circuit under test and temperature influence. Historically the pass and fail states are evaluated by a tester that

A single cell failure (SCF) is a common fail signature in dynamic random access memories (DRAMs). Generally write and read problems can be observed if a cell capacitor is not connected properly to its bitline. If the critical resistance of this conne
