Abstract:
A substrate for semiconductor device includes a substrate, a reaction layer provided on a back surface of the substrate, a transmission preventing metal having a transmittance with respect to red light or infrared light lower than that of the substrate and a material of the substrate being mixed in the reaction layer, and a metal thin film layer formed on a back surface of the reaction layer and formed of the same material as the transmission preventing metal.

Claim (Index 1):
A method of manufacturing a substrate for semiconductor device, comprising:\n a step of forming on a back surface of a substrate a metal thin film layer having a transmittance with respect to red light or infrared light lower than that of the substrate; and a reaction step of diffusing a material of the metal thin film layer into the substrate by heating the substrate and the metal thin film layer so that a reaction layer is formed in which a material of the substrate and the material of the metal thin film layer are mixed with each other.
