Title: Mos transistor and manufacture thereof
Inventor: INUISHI MASAHIDE
IPC: H01L21/265
Filed: 1988-02-19
Abstract: PURPOSE:To reduce parasitic resistance and thereby to decelerate element degradation attributable to hot carriers hy a method wherein a medium impurity concentration active layer is formed on the MOS transistor drain side only by ion implantation accomplished so askew that the active layer may be screened by the gate electrode against ion implantation. CONSTITUTION:A low concentration N<-> region 4 is formed to overlap with a gate electrode 8, on the side of the drain 5 only. In this process, with a resist gate electrode 3 serving as a mask, N-type impurity ions are implanted for the formation of an N<->-type impurity layer 4', the implantation being accomplished with the substrate in rotation. This method improves the triode region in its performance because of the parasitic resistance being decreased owing to the formation of a charge accumulation layer, and performance degradation due to hot carriers may be suppressed because an N<->-type layer is positioned under a gate electrode.

IPC: B22D11/124
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To smoothly execute drawing-out of a low carbon steel billet and to improve the center segregation in a high carbon steel by making a specified value or higher of secondary cooling quantity density for cast billet in the range of a specified length from the lower end of a mold when the steel billet having a specified value or lower of carbon content is cast. SOLUTION: In a continuous casting method for casting the steel having <=0.04 wt.% carbon content into the billet, the secondary cooling water quantity density for cast billet is regulated to >=0.4 m3/m2/s in the range of 300 mm length from the lower end of the mold 1. In such a way, in the case of lowering the surface temp. of the cast billet just below the mold to <=1100 deg.C, the development of bulging is restrained by increasing the high temp. strength of a solidified shell and the drawing-out of the cast billet from the mold can be improved. Further, in the continuous casting method which casts the steel having >=0.04 wt.% carbon content into the billet and executes light rolling reduction during casting, the secondary cooling water quantity density for cast billet is regulated to >=0.3 m3/m2/s in the range of 300 mm length from the lower end of the mold 1.  In this way, the center segregation in the cast billet can be improved with the light rolling reduction.
