Patent ID: 8664116

Claim:
A method of heating a substrate of silicon to grow a silicide, said method comprising the steps of: (a) implanting ions into said substrate to amorphize an ion implantation region in said substrate; (b) depositing a metal film on the amorphized ion implantation region; (c) heating said substrate with said metal film formed thereon at a predetermined preheating temperature; (d) irradiating said substrate with light to increase the temperature of a front surface of said substrate from said preheating temperature to a target temperature for a time period in the range of 1 to 20 milliseconds; and (e) irradiating said substrate with light to maintain the temperature of the front surface of said substrate within a ±25° C. range around said target temperature for a time period in the range of 1 to 100 milliseconds, said step (e) being performed after said step (d).
