Challenges in testing TSV-based 3D stacked ICs: Test flows, test contents, and test access

摘要

Three-dimensional stacked ICs (3D-SICs) based on Through-Silicon Vias (TSVs) have many attractive benefits and hence are quickly gaining ground. Testing such products for manufacturing defects is still fraught with many challenges. This paper provides an overview of those challenges and their emerging solutions, categorized in the areas of (1) test flows, (2) test contents, and (3) test access.
