Title: Method and apparatus for manufacturing semiconductor device
Inventor: TOMIYAMA TOMOHIKO
IPC: H01L21/265
Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To control the depth of a junction by suppressing excessively rate- increased diffusion when a shallow junction is formed in the manufacturing process of a MOSFET.  <P>SOLUTION: A semiconductor substrate after ion implantation is exposed to high-density plasma and then subjected to heat treatment for activation. When the semiconductor substrate is exposed to the high-density plasma, a temperature becomes high only on the extreme surface of the substrate and quickly drops along the thickness of the substrate, so that this property is used to repair a spot defect with heat generated on the surface without advancing diffusion. Activating heat treatment is carried out after the spot defect is repaired, and since the diffusion along the thickness is not advanced by the excessively rate-increased diffusion, the junction which has exact desired thickness can be formed.  <P>COPYRIGHT: (C)2004,JPO
