Title: Manufacture of semiconductor integrated circuit device
Inventor: SHIMA AKIO
IPC: H01L21/26
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To improve evenness in the in-surface temperature of a semiconductor wafer, in an RTP (lamp heating) technology. SOLUTION: A temperature is raised at such speed as to increase stepwise by at least two times until it reaches a final specified temperature Tf, and the speed is sequentially decreased until reaching the final specified temperature Tf. A power balance for a lamp is set for each temperature-raising stage. The power balance for the lamp for each temperature-raising stage is adjusted by evaluating the distribution in a wafer surface for the thickness of a wet oxide film formed on the surface of a dummy wafer.
