Abstract
Clear correlation between dislocation distribution and FET threshold voltage distribution in undoped LEC GaAs was observed directly for the first time by automatic computer-controlled measurement of drain-source current (I ds) and threshold voltage (V th). FETs fabricated in the high EPD area, which covers the center and the periphery of (100) wafers, showed high I ds and low V th, whereas FETs fabricated in the low EPD area showed low I ds and high V th.Keywords
