Abstract: PURPOSE:To enable the growth of an epitaxial layer in a short time, by sealing a raw material gas in a vessel having higher pressure than the pressure in a reaction tube, sealing a purge gas in a vessel having higher pressure than the pressure of the raw material gas and supplying the gases from both supplying systems to a reaction tube. CONSTITUTION:A raw material gas is supplied to a reaction tube at a constant feeding pressure higher than the pressure in the reaction tube and a purge gas is supplied at a pressure higher than the feeding pressure of the raw material gas. The raw material gas is supplied in the region between valves 2, 3, 4 under a constant pressure by opening the valve 3 and sealed in the above region by closing the valve 3. When the valve 1 is closed, the purge gas is supplied between the valves 1, 2 under a definite pressure and is sealed between the valves 1, 2 by closing the valve 1. Both gases are blasted into the reaction tube by opening the valves 2 and 4 at the same time and the supply of the gases is terminated when the pressure of the gas is equilibrated with the pressure in the reaction tube. In the above process, the supplying pressure of the purge gas is set higher than the supplying pressure of the raw material gas to shut the flow of the purge gas in the case of closing the valve 4.

Abstract: PURPOSE:To prevent the substrate destruction on the wall surfaces of the V-grooves formed on a substrate surface by finishing the wall surfaces on one side of the grooves by a 2nd diamond grinding wheel in which one of the opposite grinding wheel surfaces has a spacing from the wall surfaces of the grooves. CONSTITUTION:The continuous plural grooves 6... are formed on the surface of the substrate 5 by the 1st diamond grinding wheel 2 having the angle alpha formed by the surface of the grinding wheel surface and a center line. The wall surfaces 7 of the grooves 6 are then finished in the state in which the one grinding wheel surface 3 has the spacing from the wall surfaces 7 of the grooves by using the 2nd diamond grinding wheel 1 having the shape which is smaller in the angle beta formed by one of the grinding wheel surfaces 3 facing each other and the center line of the grinding wheel than the angle alpha formed by the other grinding wheel surface 4 and the center line. Namely, while the one grinding wheel surface 4 finishes the wall surfaces 7 of the grooves 6 to a prescribed surface roughness, the other grinding wheel surface 3 does not come into contact with the wall surfaces 7 and does not polish the wall surfaces 7 of the grooves and, therefore, the generation of the glazing and loading of the diamond is obviated. The substrate destruction on the wall surfaces of the grooves is prevented in this way.
