Title: Annealing method for ion implanted layer
Inventor: ITO KAZUHIKO
IPC: H01L21/268
Filed: 1986-05-22
Abstract: PURPOSE:To prevent diffusion of implanted ions in a short time and to suppress the yield of secondary defects, by using light, whose intruding depth in a semiconductor wafer is the same as the thickness of an ion implanted layer as a character of the wavelength of the light, for heating the ion implanted layer for a short time. CONSTITUTION:Annealing is performed by the projection of laser light 3, whose wavelength can be changed, in order to heat an ion-implanted layer 2. The wavelength of the laser light 3 is selected so that the intruding depth of laser light into a semiconductor wafer 1 is the same as the thickness of the ion- implanted layer 2. Therefore, even if the ion implanted layer 2 is thick, the laser light 3 reaches the deep part of the ion-implanted layer 2. The entire body of the ion-implanted layer 2 is heated immediately after the projection of the laser light 3 without using thermal diffusion. Thus the temperature gradient in the thickness direction of the semiconductor wafer 1 at the initial period of the projection of the laser light 3 can be suppressed. The yield of the secondary defects can be prevented. The annealing of the ion-implanted layer 2 can be achieved in a short time.
