Abstract:
1. An apparatus for manufacturing a nitride semiconductor device, comprising: an excitation light irradiation section configured to irradiate excitation light onto a nitride semiconductor thin film out of a layered product wherein said nitride semiconductor thin film is deposited on a silicon carbide substrate; a defective part specification section configured to specify a position of a defective part of said silicon carbide substrate based on the defects of said silicon carbide substrate generated in said nitride semiconductor thin film by said excitation light; a layered product processing section configured to process an area other than said defective part among said layered product and forming a processed layered product; a cutting section configured to cut said layered product including said processed layered product at each predetermined device dimension to create a plurality of chips; and an elimination section configured to eliminate chips other than the chips including said processed layered product from said chips.
