Title: Schottky barrier diode
Inventor: TAKAGI TOSHIO
IPC: H01L29/872
Filed: 1985-07-01
Abstract: PURPOSE:To avoid the necessity for enlarging the chip size because of forming recognition patterns, by forming a plural of the recognition patterns formed of a material having a reflection factor different from that of the metal, on the top metal face of the electrode section. CONSTITUTION:A Schottky barrier diode comprises of a semiconductor substrate 11, an oxide film 12 and a metal electrode 13. After a polyimide film is deposited on the surface of the metal electrode 13, etching forms recognition patterns 14 at given positions (four corners). Since the reflection factor of the polyimide film is different from that of the metal, the recognition patterns can be identified with the difference between the reflection factors, enabling to operate automatically the bonding. Since the recognition patterns 14 are identified with the difference between the reflection factors, a P-type diffusion layer is not required to be formed for avoiding the electric field concentration. Accordingly, it is not required to enlarge the chip size, so a low-cost Schottky diode can be provided.

Title: Forging die
Inventor: HIROWATARI MASATAKA
IPC: B21J13/02
Filed: 1988-06-13
Abstract: PURPOSE:To improve dimensional accuracy of the product and to prevent uneven wear of driving members by expanding the widths of flash land parts of the upper and lower dies of the smaller reaction force sides for the pressurizing center of the upper die. CONSTITUTION:In case the center O1 of the composite projected area 2A of the upper die 2 deviates from the pressurizing center O2 of the upper die, that is to say, the right side reaction force for the upper die 2 is small, the flash land 2b of the upper die is expanded to form an expanded land part 2c. Further, for the lower die 5, an expanded land part 5b is formed on the position corresponding to the upper die 2. As the result, the center position O1 of the composite projection area including the projection part of the expanded part 2c moves in the right direction to nearly accord with the pressurizing center position O2 of the driving members. By this method, a distribution of the reaction force for the upper die 2 is equalized to the pressurizing center O2. Therefore, the flash thickness is equalized and the product accuracy is improved. By eliminating the load deviation, its uneven wear is prevented.
