Title: Covered tungsten tool
Inventor: OKUZUMI AYANORI
IPC: C23C16/27
Filed: 1986-10-14
Abstract: PURPOSE:To obtain a high bonding strength sufficient for a grinding tool or a wear resistant tool, by covering a tungsten base member with a diamond layer by a thickness of 1 to 100mum. CONSTITUTION:A tungsten has a rigidity with which it may bear a diamond cover layer without hindrance, and is excellent in heat-conductivity so that the dissipation of heat is satisfactory. Further the thermal expansion coefficient is lowest among various kinds of metal so that the peel-off caused by the difference in thermal expansion between tungsten and diamond may be restrained, and therefore, it may be subjected to vacuum heat-treatment at a temperature of about 1,000-1,400 deg.C while the diamond cover layer is restrained from being turned into graphite. A diamond cover layer 2 is applied on a tungsten base member 1 by a thickness of 1 to 100Xm with the use of chemical vapor deposition, plasma-atmospheric vapor deposition, ion beam vapor deposition or the like, Thereby it is possible to obtain a high bonding strength between the diamond cover layer 2 and the tungsten base member 1.

Filed: 1983-12-26
Abstract: PURPOSE:To provide a semiconductor substrate which has a recrystallized silicon film of high crystallization quality on a insulating substrate, by using the material which has a linear heat expansion rate within the specified range as the insulating substrate. CONSTITUTION:A polycrystalline silicon film 2 is deposited on an insulating substrate 1 and a silicon dioxide film 3 is then covered thereon. If a wafer 5 is moved which is being placed on a carbon susceptor 4 which functions as a heater in a radio frequency induction heating process, the polycrystalline Si 2 melts like a belt which moves relatively as the wafer 5 moves and recrystallization caused by the so-called zone melting proceeds, when the polycrystalline Si 2 passes through the section 7 having a higher temperature over the melting point of Si. As the substrate 1, one which has a linear heat expansion rate close to that of Si, i.e., from 2X10<-6>-8X10<-6>/ deg.C, and has a high melting point, may be appropriately used.
