  • Patent number: 9412587
    Abstract: A method of manufacturing a semiconductor device includes alternately performing supplying a first process gas containing silicon and a halogen element to a substrate having a surface on which monocrystalline silicon and an insulation film are exposed and supplying a second process gas containing silicon and not containing a halogen element to the substrate, and supplying a third process gas containing silicon to the substrate, whereby a first silicon film is homo-epitaxially grown on the monocrystalline silicon and a second silicon film differing in crystal structure from the first silicon film is grown on the insulation film.
    Type: Grant

  • Publication number: 20140295648
    Abstract: Disclosed is a method of manufacturing a semiconductor device including: a process of transferring a substrate into a processing chamber; a first gas supplying process of supplying a B atom-containing gas into the processing chamber; a first purging process of purging an inside of the processing chamber under an atmosphere of the B atom-containing gas supplied in the first gas supplying process; a second gas supplying process of supplying an Si atom-containing gas into the processing chamber to form a non-doped Si film on the substrate, after the first purging process; and a second purging process of purging the inside of the processing chamber under an atmosphere of the Si atom-containing gas.

  • Patent number: 8673076
    Abstract: Disclosed is a substrate processing apparatus which comprises reaction tubes (3,4) for processing multiple substrates (27), a heater (5) for heating the substrates, and gas introducing nozzles (6,7,8,9,10) for supplying a gas into the reaction tubes. Each of the gas introducing nozzles (6,7,8,9) is structured so that at least the channel cross section of a portion facing the heater (5) is larger than those of the other portions.
