Title: Heat treatment method
Inventor: KAWARAZAKI HIKARU
IPC: H01L21/265
Filed: 2019-08-07
Abstract: To provide a heat treatment method capable of measuring a surface temperature of a substrate with accuracy.SOLUTION: A semi-conductor wafer is heated by a flash light irradiation from a flash lamp after a preheating by a halogen lamp. A temperature of a semi-conductor wafer just before the flash light irradiation is measured by a lower radiation thermometer. Since a light reception angle to the semi-conductor wafer of the lower radiation thermometer is 60 degrees or more and 89 degrees or less, the lower radiation thermometer can accurately measure the temperature of a back surface of the semi-conductor wafer regardless of a kind of a film formed on the back surface of the semi-conductor wafer. At the time of the flash light irradiation, a rising temperature of a front surface of the semi-conductor wafer is measured by an upper radiation thermometer. A front surface temperature of the semi-conductor wafer is calculated by adding the rising temperature of the front surface of the semi-conductor wafer at the time of the flash light irradiation measured by the upper radiation thermometer to the back surface temperature of the semi-conductor wafer measured by the lower radiation thermometer.SELECTED DRAWING: Figure 11
