Title: Radiation board material
Inventor: KAYA FUMITAKA
IPC: H01L23/12
Filed: 1992-08-26
Abstract: PURPOSE:To improve the workability and the thermal conductivity by integrally stacking a metal sheet made of copper, copper-tungsten or copper-molybdenum and a metal net made of molybdenum or tungsten. CONSTITUTION:A metal sheet 1 made of a Cu sheet, a Cu-W sheet or a Cu-Mo sheet containing 40wt.% or more of Cu and a metal net 2 formed by knitting W wires or Mo wires are stacked and an integrally stacked sheet is formed by a heating and a rolling. Since a wire material serves as a control material of the thermal expansion coefficient, the stacked sheet is superior to a sheet formed by a powder sinter method or an impregnation method in control of the thermal expansion coefficient. Also, since the W wires or Mo wires are formed in a net, the anisotropy of the thermal expansion coefficient and thermal conductivity in a plane direction is small. Further, since the workability of rolling and blanking is good, it is suitable for a mass production and a manufacturing cost can be remarkably reduced.

IPC: H01L21/027
Filed: 1985-11-11
Abstract: PURPOSE:To separate a wafer from a mask rapidly without fail doing no damage to the wafer by a method wherein a vacuum chuck for adsorbing the wafer is separated from the wafer in non-adsorbing state and then the mask is vacuumized downward to be bent upward so that a part or all part of wafer may be peeled off. CONSTITUTION:A wafer 1 and a mask 5 are vacuum-adsorbed and then the wafer 1 is pushed up by a chuck 3 to augment adhesion for exposure process. After finishing the exposure processing, the chuck 3 only is lowered with the vacuum state held as it is. The mask 5 starts bending upward due to the vacuum adsorption (F1) making gaps from the wafer 1. Resultantly, the wafer 1 adhered to the mask 5 can be peeled off from the peripheral parts. Finally the wafer 1 completely peeled off falls down on the chuck 3 to be reset to the original position by releasing the vacuum adsorption.
