Abstrakt: Proposes a technique for whole-wafer etch-pit density (EPD) mapping in gallium arsenide (GaAs). Derivation of the quantitative relationship between fractional transmission and EPD; Illustration of an automated absorption apparatus useful in EPD mapping; Property of the pits formed on an etched GaAs surface.
