Title: Manufacture of semiconductor device
Inventor: SATO HIROSHI
IPC: H01L29/78
Filed: 1995-02-16
Abstract: PURPOSE: To check the diffusion of impurities from a polycrystalline silicon layer to a silicide by laminating an amorphous TiBx layer as the second layer. CONSTITUTION: An oxide film 12 is formed on a semiconductor substrate and then a polycrystalline silicon as the first layer is formed on the oxide film 12 to selectively implant impurities in the polycrystalline silicon layer 14. Next, an amorphous TiBx layer 16 as the second layer and the first melting point metallic silicide 18 as the third layer are laminated. Next, the WSix layer 18 and the amorphous TiBx layer 16 are processed after a specific gate electrode wiring pattern. Later, the impurities are ion-implanted in the substrate to shallowly form a low concentration diffused region as well as deeply forming a high concentration diffused layer in the substrate distant from the gate electrode.  Through these procedures, during the heat treatment step, the impurities can not be diffused in the amorphous TiBx layer 16 existing between the polycrystalline layer 14 and the silicide layer 18 so that the impurities may be piled up on the interface between the polycrystalline silicon layer 14 and the amorphous TiBx layer 16.

To be more precise, a current is made to flow in the direction of film thickness of the seed when the current is applied between the surface and the rear of the sample. At this time, the seed part only has the electric conductivity on the surface and the rear of the sample, the current made to flow from the obverse is concentrated on the seed part, Joule heat is generated on the seed part only, and the temperature on the seed part is made higher than the SOI part. Subsequently, the application of the current is discontinued, and the difference in temperature between the seed part and the SOI part can be reduced by performing a beam irradiation under the state wherein said seed part is heated up.
