Abstract
PURPOSE: To improve the thickness distribution of each grown layer along the flowing direction of a reactive gas, in the title device contg. many wafers for manufacturing a semiconductor device, by making the temp. of both ends of the reaction region lower than that of the center and by alternately changing the gas flowing direction.
CONSTITUTION: Substrate Si single crystal wafers 3 are mounted on susceptor 2 in reaction tube 1, and susceptor 2 is heated to a fixed temp. of 400W1200°C with heaters 4 while flowing H2. At this time, RF coils are made tight in the central part and loose in the peripheral part to give a temp. gradient. Reactive gas 5 of SiH2Cl2 mixed into H2 is then flowed to vapor phase grow Si on wafers 3. The reactive gas flowing direction is alternately changed by operating feed gas change- over valves 6,8 and exhaust gas change-over valves 7,9. By this method the thickness distribution of each polycrystalline Si layer on wafers 3 is improved, and autodoping is uniformed every wafer in case of Si epitaxial growth.
