Title: Apparatus for manufacturing semiconductor substrate
Inventor: MIZUKI TOSHIO
IPC: H01L21/205
Filed: 1986-09-11
Abstract: PURPOSE:To obtain a desirable high-quality epitaxial layer with a relatively low flow of material gas, by ejecting a second gas upwards to between a nozzle and a reaction furnace. CONSTITUTION:Material gas is spouted together with carrier gas vertically upwards from an injection tube 31 of a nozzle 18 at a predetermined pressure, The gas is dispersed through a net 32 of a guide section 30 and converted into cylindrical gas flow by a columnar jig 35. Purge gas is introduced into a reaction tube 16 through a gap between an injection port provided in a flange section 19 and the injection tube 31 of the nozzle 18. Thus, a coaxial cylindrical laminar flow having the center on the axis of a base 33 is caused to flow upwards between the reaction tube 16 and the base 33. A reaction product produced by the first gas is thereby prevented from adhering on the inner walls of the reaction furnace. Further, upward buoyancy occurs in the first gas supplied to near a holding member for holding a semiconductor substrate because there is a difference in temperature between the holding member and the inner walls of the reaction furnace. Consequently, a gas flow rate as desired can be obtained with a relatively low flow.

Filed: 1983-11-14
Abstract: PURPOSE:To assure quick braking performance to a crank shaft in the stage of stopping operation by supplying selectively two stages of fluid pressure to a piston chamber formed in order to press a piston to a drive plate side. CONSTITUTION:An air pressure having a pressure value (c) is supplied to a piston chamber 14 to move quickly a piston 13 to a drive plate 3 side and to start a crank shaft 1 in press contact with the plate 3 in the stage of starting operation.
