Abstract:
A front surface of a semiconductor wafer is rapidly heated by irradiation of a flash of light. Temperature of the front surface of the semiconductor wafer is measured at predetermined intervals after the irradiation of the flash of light, and is sequentially accumulated to acquire a temperature profile. From the temperature profile, an average value and a standard deviation are each calculated as a characteristic value. It is determined that the semiconductor wafer is cracked when an average value of the temperature profile deviates from the range of ±5σ from a total average of temperature profiles of a plurality of semiconductor wafers or when a standard deviation of the temperature profile deviates from the range of 5σ from the total average thereof of the plurality of semiconductor wafers.

Claim (Index 11):
A heat treatment apparatus for heating a substrate by irradiating said substrate with a flash of light, the heat treatment apparatus comprising:\n a chamber that houses a substrate; a flash lamp that irradiates a front surface of said substrate housed said the chamber with a flash of light; a radiation thermometer that measures temperature of the front surface of said substrate by receiving infrared light emitted from the front surface; a profile acquiring unit that acquires a temperature profile of temperature of the front surface of said substrate, measured by said radiation thermometer for a predetermined period after irradiation of a flash of light from said flash lamp is started; and an analyzing unit that analyzes said temperature profile to detect a crack of said substrate.
