Title: Quartz crucible for pulling up silicon single crystal
Inventor: MATSUO HIDEYASU
IPC: C30B29/06
Filed: 1981-05-15
Abstract: PURPOSE: To obtain an Si single crystal with few defects in the crystal structure in a high yield by coating the surface of a quartz crucible used in a device for pulling up an si single crystal with a silicon nitride film to prevent chips of quartz glass from peeling off the crucible.  
     CONSTITUTION: A quartz crucible 12 for pulling up an Si single crystal is manufactured by coating the inner wall 2a of an ordinary quartz crucible 2 with a high purity dense silicon nitride film 19 by vapor deposition. By regulating the thickness of the film 19 to ≤0.5μm, the amount of suspended foreign matter is reduced when an Si single crystal is pulled up, and the single crystal yield is enhanced considerably. The effect of the film 19 is independent to the crystalline or amorphous state. The crucible 2 is mounted on a support stand 18 in a quartz reaction tube 14, and the deposition of the film 19 is carried out while rotating the stand 18 so as to make the film 19 uniform. The deposition is carried out at 950W1,350°C under low pressure in an atmosphere contg. SiCl 4 , H 2  and NH 3 .

Title: Gold alloy thin wire for semiconductor elements and bonding method thereof
Inventor: FURUKAWA KIYOSHI
IPC: H01L21/60
Filed: 1989-03-24
Abstract: PURPOSE:To improve the reliability by obtaining the resistance to long-time use at high temperature by using a material including one or plural kinds of Ti, Hf and Zr within the specified range of weight ppm in total and having the rest of Au and unavoidable impurities. CONSTITUTION:This gold alloy thin wire includes one or plural kinds of Ti, Hf and Zr of 100-10000ppm in total and the rest is composed of Au and unavoidable impurities. If this content is under 100ppm, when a semiconductor device is used practically, there is no effect that the generation of intermetallic compound in a bonding part between the wire and an Al electrode is restrained at the time of use at high temperature. Meanwhile, if the content is beyond 10000ppm, work-hardening appears abruptly in consequence on the deformation of a ball part formed at the end of the wire, even if the bonding is performed in an insert atmosphere such as a vacuum. Accordingly, the roundness declines, the bonding becomes difficult, and the connecting strength decreases. By this method, the excellent resistance to high temperature can be obtained and the improvement in reliability is contrived.

IPC: G03F7/20
Filed: 1995-03-30
Abstract: PURPOSE: To reduce cost by minimizing the deterioration of the processing capability of an exposing device in the removal of photoresist around a wafer. CONSTITUTION: In forming a pattern on the pattern forming part on a wafer with reduction projection exposure device and removing photoresist at the peripheral part of the wafer where the pattern is not formed, only one reticle for pattern formation is used without changing the reticle.

Abstract: PURPOSE:To obtain a notion map generating device which can flexibly express the knowledge by providing a phase where the non-resemblance degree is gradually changed and then the arranging position of the symbols is also gradually changed and another phase where the symbols are rearranged based on an initial state. CONSTITUTION:The phases are roughly divided into two types, that is, a phase the non-resemblance degree is corrected and a notion map obtained based on the corrected non-resemblance degree is gradually corrected and a phase where the non-resemblance degree is calculated again from an initial state. In the former phase, a calculation means 3 calculates a difference between a vector where the ideal non-resemblance degrees inputted by a non-resemblance correction means 1 are arranged in a certain order and a vector where the actual non-resemblance degrees are arranged. In such a system, the calculation value is comparatively reduced but a minimum solution may possibly produced. Meanwhile a better minimum solution may possibly obtained together with the larger amount of calculation in a system where the non-resemblance degrees are calculated again by a recalculation start means 2 based on the initial arrangement.
