Title: Source introducing mechanism for cvd apparatus
Inventor: SAKAI HIDEO
IPC: H01L21/285
Filed: 1981-12-25
Abstract: PURPOSE:To obtain a uniform film thickness in the source introducing mechanism for a CVD apparatus, by making the horizontal width of the source  introducing part much larger than the wafer width. CONSTITUTION:A multiplicity of wafers 3 on which a film is formed by a CVD treatment are mounted on a support plate 2 in a processing oven 1. The oven 1 is cylindrical and has a source introducing part 4 for introducing a source into the oven 1. The introducing part 4 extends horizontally in the oven 1, and an outlet 5 is provided on the side opposite to the inlet part 4. The end portion of the source introducing part 4 is formed into a larger-width part 6 which extends horizontally. A source inlet 7 is horizontally disposed on the end surface of the larger-width part 6 and is constituted by one opening formed into a slit shape which is thin in the horizontal direction. By this constitution, when a metal source is introduced into the oven 1, the source from the inlet 7 is uniformaly diffused over the surfaces of the wafers 3, thereby allowing the formation of a film having a uniform thickness.

Title: Cleaning method of silicon semiconductor substrate
Inventor: HABUKA HITOSHI
IPC: H01L21/306
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To remove organic matter and metallic impurities on a silicon semiconductor substrate, while preventing the regrowth of a natural oxide film and thermal diffusion of metallic impurities. SOLUTION: H2 gas which can maintain reducing atmosphere is used as carrier gas throughout. Sticking organic matter is decomposed by HF gas and metallic impurities are changed to metallic chloride by HCl gas. Since product of high vapor pressure can be obtained from a starting substance in any treatment, it is gasified in H2 gas atmosphere of higher temperature. The temperature of the whole process can be lowered to 1000 deg.C or lower. When these impurites stick on an oxide film, an oxide film can be removed by carrying out HF gas treatment in a temperature range lower than 100 deg.C wherein absorbed water of an oxide film can be held before the above treatment. If HF gas treatment and HCl gas treatment are carried out at a temperature of 100 deg.C or higher from the beginning, an oxide film can be left.
