Title: Method for joining different kinds of metallic material
Inventor: SHIBATA YOSHINORI
IPC: B23K11/30
Filed: 2002-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a resistance welding method for different kinds of metallic material without largely changing the conventional production process and without producing an intermetallic compound by using no intermediate layer and no cladding material.  <P>SOLUTION: The resistance welding method for different kinds of metallic material is characterized in that a minute molten portion is produced between the different kinds of material by causing high current to flow for very short period of time and simultaneously, high pressure force is applied to the molten portion to scatter the molten portion as dust, and a solid-phase joined part is obtained by the contact of clean metal surfaces with each other and the diffusion of atoms. Thus, if this method is applied to the welding process, for example, for a car body, since the welding of the different kinds of metallic material can be performed without requiring a large change in the conventional processing line, this method can efficiently cope with the demand for weight saving of the car.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device in which damage to a gate insulation film is controlled and prevented.  <P>SOLUTION: It is found that the end point can surely be determined at timing T<SB>1</SB>when the etching of a polysilicon film 3 of an n-type region 5 is completed, because, when a changing rate b/a of light emitting intensity in Fig.(a) becomes 0.3 or more, a change (b) of light emitting intensity becomes extremely large. Moreover, as an occupying rate of n-type region 5 in the whole region is increased, the changing rate b/a of light emitting intensity becomes larger. Namely, Fig.(b) illustrates that, when the n-type region 5 is widened, the end point of the timing T<SB>1</SB>when the etching of the polysilicon film 3 in the n-type region 5 is completed can be easily determined, and the etching can surely be stopped at the timing T<SB>1</SB>when the etching of polysilicon film 3 of the n-type region 5 is completed. Therefore, it is preferable to increase the n-type region 5, where the changing rate b/a of light emitting intensity becomes 0.3 or more in Fig. 7(b), up to 50% or larger of the whole region.  <P>COPYRIGHT: (C)2004,JPO
