Abstract
A semiconductor device inspection apparatus includes: a light sensor that detects light from a semiconductor device as a DUT to which an electric signal has been input; an optical system that guides light from the semiconductor device to the light sensor; and a control device electrically connected to the light sensor. The control device includes: a data reading unit that reads mask data indicating a mask layout of the semiconductor device; a search unit that searches for a position of a transistor in the semiconductor device on the basis of polygon data of a gate layer of the semiconductor device included in the mask data; a setting unit that sets the searched position of the transistor as an optical measurement target position; and a measurement unit that performs optical measurement for the set optical measurement target position to acquire a measurement result.
