Claim 8:
9. The semiconductor device inspection method according to claim 1, further comprising:
determining, based on the second information, whether or not to perform a third inspection irradiation on the area to be inspected, the third inspection irradiation being for irradiating the area to be inspected with light while the test signal is being input to the semiconductor device;
when it is determined that the inspection irradiation is to be performed, performing the third inspection irradiation on at least one portion in the area to be inspected of the semiconductor device to which the test signal is being input, the at least one portion where the third inspection irradiation is to be performed, being different from the portions where the first inspection irradiation and the second inspection irradiation have been performed; and
outputting third information indicating presence or absence of a defective portion in the entire of the area to be inspected, based on an output signal output from the semiconductor device during performing the third inspection irradiation, and
wherein the at least one portion where the third inspection irradiation is performed is located between one portion where the first inspection irradiation has been performed and one portion where the second inspection irradiation has been performed.
