Title: Method of bonding metal having different physical property
Inventor: JIEI SHII ERANDAA
IPC: B21D39/03
Filed: 1989-02-16
Abstract: PURPOSE: To make a second metal flow and to fix one part of a first metal to the second metal by hitting a second punch having a larger dimension than that of a first punch to the second metal and pushing back one part of the first metal and a slug of the second metal toward the surface of the second metal. CONSTITUTION: A force is applied to the punch 22 and a spring steel made disk 11 is pushed into a soft magnetic iron member 12. The slug 32 is pushed out and into a bottom die 30 by this pushing. When the punch 22 is removed, the first metal i.e., the spring steel made disk 11 which is pushed into the second metal is left. Next, when the second punch 35 is pushed down toward the soft magnetic iron member 12 and a force is applied to the punch 35, the slug 32 is pushed back upward. A fold is formed in a part 16' of the soft magnetic iron member 12 by pushing back of the slug 32. Thus, the spring steel made disk 11 is firmly fixed into the soft magnetic iron member 12 as the first metal incorporated into the second metal member 12 being magnetic iron through two processes.

Title: Mos type transistor and manufacture thereof
Inventor: KURIYAMA HIROKO
IPC: H01L29/78
Filed: 1990-02-15
Abstract: PURPOSE:To ensure high reliability of an LDD structure by forming an LDD region and then enabling a high melt-point material film to grow on a polysilicon, enabling the polysilicon and the high melt-point material film to be subjected to eutectic for forming a silicide, and by forming a gate electrode with the polysilicon and the silicide. CONSTITUTION:LDD regions 4 and 5 with less impurity concentration are formed by injecting n-type impurities with a small amount of injection. Then, after an Ar is injected onto a gate electrode 3, a high melt-point material film 10 is allowed to grow and heat treatment is performed, thus enabling the high melt-point material film and a silicon to react on the gate electrode and on a gate electrode side wall for forming a silicide film 9 selectively. Then, after an oxide film and the high melt-point material film on the surface of the LDD region are eliminated by etching, an insulation CVD film is allowed to grow on it. If anisotropic etching is performed, the insulation CVD film remains on the side wall of the gate electrode, which becomes a spacer 6, thus obtaining a sufficient effect with an LDD structure and ensuring a stable reliability.
