Patent JP-S6046029-A (JP)
Title: Equipment for manufacturing semiconductor
Inventor: NAKAZATO NORIO
IPC: H01L21/205
Filed: 1983-08-24
Abstract: PURPOSE:To improve the uniformity of treating a wafer by supplying gases of equal speeds and equal amounts to the surface of the wafer placed on a table from opposed electrodes. CONSTITUTION:Gas from a gas supply unit is supplied to a gas passage 11, sequentially passeed through the first vacant chamber 42 and the second vacant chamber 43 to a discharge space 40, i.e., the surface of a wafer 50. In this case, the gas supplied to the chamber 42 is flowed radially in the chamber 42. In this case, pressure loss occurs, gas velocity passing through a hole 25 from the center of other dispersing plate 23 toward the outer edge gradually becomes small, but since the opening area of the hole 24 becomes sequentially large from the center toward the outer edge, the supply amount of the gas to the chamber 42 per unit area of the hole 25 becomes equal both at the center and at the periphery of the plate 23. Therefore, the gas pressure becomes constant in the all area of the chamber 43 in the chamber 43, and gas velocity from the hole 24 of the plate 22 becomes equal velocity irrespective of the position of the hole 24.

Filed: 1990-06-13
Abstract: PURPOSE:To efficiently grow a thin film in a state where the speed and remaining element concentration in a concentration boundary layer are reduced in a moment and the occurrence of surface roughening is prevented by tentatively reducing the pressure in a reactive container when the raw material gas fed to the container is switched to another. CONSTITUTION:When an AlGaAs layer is formed on a GaAs layer, the AlGaAs layer is formed by successively supplying each raw material gas of trimethyl aluminum, trimethyl gallium, and arsine from each raw material container 5-7 after pressure control is made by means of a rotary pump 13 and pressure regulating valve 14 so that the growing pressure in a reactive container 1 can become 100Torr. When the raw material gases are supplied, a valve 14 is fully opened and the pressure in the container 1 is reduced to 50Torr. Since the pressure in the container 1 is reduced to 50Torr and returned to the 100Torr immediately before the next raw material is supplied in such way, the thickness of the boundary surface between both layers can be reduced to about 3Angstrom  from about 16Angstrom  in a several seconds of growth stopping time.
