Abstract
An apparatus to be inspected is mounted on one surface of a socket board. An auxiliary inspecting apparatus for adjusting timing of write signals transmitted from a semiconductor inspecting apparatus is mounted on the other surface of the socket board. Input/output (I/O) pins of the auxiliary inspecting apparatus are connected to corresponding I/O pins of the inspected device via through holes in the socket board on a one-to-one basis. This semiconductor inspecting method is thus capable of easily suppressing the delay difference between a plurality of signals output from the semiconductor inspecting apparatus.
