Title: Fabrication of semiconductor device
Inventor: SUMI HIROBUMI
IPC: H01L21/768
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a semiconductor device having excellent characteristics in which a semiconductor region having a smooth interface can be formed along with an overlying uninsulating film. SOLUTION: After an oxide film is removed from the surface of a diffusion layer 17 and a poly-Si film 14 by etching with a liquid containing hydrofluoric acid of pH 3 or below, a Ti film is deposited and heat treated to form a TiSi2 film 21. Since the liquid containing hydrofluoric acid has pH of 3 or below, etching of crystal surface is suppressed even if the diffusion layer 17 having high donor or acceptor concentration and the poly-Si film 14 are subjected to over etching and the surface is not roughened. Furthermore, a smooth interface can be obtained because the TiSi2 film 21 is formed after etching.

The rolling control is performed by setting a roll gap based on the calculated predictive rolling load and by calculating and setting a roll circumferential speed based on the predictive advance ratio. In this method, a highly accurate rolling load and advance ratio are predicted, so that products with a highly accurate plate thickness are obtained.
