Abstract—In semiconductor manufacturing, wafer fabrication is followed by chip assembly where individual dies are assembled as a packaged chip. In between, dies are tested in terms of their electrical properties and those which fail to pass the “wafer test” are filtered out. However, some faulty dies pass the test and cause a packaged chip to fail in the final test. The inaccuracy of the …
Abstract In this paper, we propose a method to optimize the product performance instantly by utilizing the internal voltage trimming circuit for Dynamic Random Access Memory (DRAM) memory. Specifically, we first define the verification wafer as the internal voltage characteristics using the clustering technique. Second, the optimized voltage conditions are applied to a normal wafer being match…
