Title: Semiconductor wafer holding mechanism
Inventor: YAMAZAKI TAKASHI
IPC: H01J37/317
Filed: 1985-09-04
Abstract: PURPOSE:To minimize the contact thermal resistance by providing ultrafine projections on a wafer holding surface of a thermal conductive sheet. CONSTITUTION:Heat transfer is executed mainly by a contact thermal resistance in vacuum in case of 200 deg.C, but cannot except the effects of convection and radiation. Since the contact thermal resistance in vacuum becomes large if separated, for example, even 1mum, a large difference of heat dissipation occurs according to how efficiently to contact with the entire wafer. Thus, even if uniform surface pressure is not obtained on the entire surface, to contact substantially with the overall surface, it is constructed to obtain substantially uniform contacting surface pressure by utilizing the elastic force of a projection on a wafer holding surface, and the height H of the irregular surface in a cushion may be sufficient with the value of 0.1mm or less. When the value of the irregular pitch L is increased, a heat transfer route is lengthened by considering the heat transfer resistance of the wafer in a thicknesswise direction to increase the thermal resistance. Thus, the pitch is preferably set to the value near the thickness of the wafer.

Abstract: PURPOSE:To form directly a glass film having excellent uniformity on a substrate in a short period by forming the flow of a gaseous raw material and oxidizing gas in the laminar state so as to incline with respect to the substrate in a heated reaction vessel and passing an inert gas along the inside wall of the vessel. CONSTITUTION:The substrate 4 (glass or metallic silicon) is inclinedly disposed in the reaction vessel 1 heated by a heating element 2. The gaseous raw mate rial (SiCl2, GeCl2) and oxidizing gas are vertically fed into the vessel 1 from above the same by a concentrical multi-walled pipe burner 3 and are blown in the laminar state toward the substrate 4. The inside wall of the reaction vessel 1 is double-layered and the inert gas is blown from the blow-off port 11 thereof along the inside wall to prevent the sticking of the glass to the inside wall. The gaseous flow in the laminar state is thus vitrified by vapor reaction and the doped quartz glass film is directly formed on the substrate 4.
