Title: Method for manufacturing semiconductor device
Inventor: MAEKAWA SHIGETO
IPC: H01L29/78
Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To activate impurities without accompanying the occurrence of a lattice defect and a change of a shape by using phonon absorption.  <P>SOLUTION: When silicon is irradiated with a laser beam 42 having a wavelength of 16 to 17μm, multiplex phonon lattice absorption is caused. Since solid phase epitaxy in an irradiation part is completed before energy supplied by the laser beam 42 is diffused to a periphery, crystallization occurs only in a local part with which the laser beam 42 is irradiated, and the crystallization does not occur in a part with which the beam is not irradiated. Thus, excessive heat absorption is not caused, and the phase transformation of local melting/solidification does not occur.  <P>COPYRIGHT: (C)2004,JPO
