Patent ID: 7531255

Claim:
A thermal treatment apparatus provided on a substrate comprising: (i) a heat generating section which includes: a heat generating layer which is made of a material containing Au, and whose electric resistance increases as its temperature increases; a diffusion preventing layer which contacts one surface of the heat generating layer to prevent diffusion of the material of the heat generating layer due to heat generation of the heat generating layer; and a cohering layer disposed between the substrate and the diffusion preventing layer; (ii) a power supply section which at least one of: (a) applies a voltage to the heat generating section, and (b) passes a current through the heat generating section, to heat the heat generating section; and (iii) a control section which reads a resistance of the heat generating section from the at least one of the voltage and the current applied to the heat generating section, and reads a temperature of the heat generating section based on the resistance, and which controls the power supply section to control the temperature of the heat generating section.
