  • Publication number: 20060138475
    Abstract: The invention relates to a method of manufacturing a semiconductor device (10) with a substrate (1) and a semiconductor body (2) comprising a first (N-MOS)PET (3) with a first channel region (3A) and a first gate electrode (3B) which includes a first conductor and which is separated from the channel region by a dielectric layer (4), and comprising a second (P-MOS)FET (5) with a second channel region (5A) and a second gate electrode (5B) which includes a second conductor that is different from the first conductor and which is separated from the channel region (5A) by a dielectric layer (4), wherein to form the gate electrodes (3B, 5B) a first conductor layer (33) is deposited on the semiconductor body (2) provided with the dielectric layer (4), which layer (33) is subsequently removed outside the first channel region (3A) after which a second conductor layer (55) is deposited on the semiconductor body (2), and wherein before the first conductor layer (33) is deposited, an intermediate layer (6) is deposited on

  • Patent number: 6551409
    Abstract: A method for removing organic contaminants from a semiconductor surface whereby the semiconductor is held in a tank and the tank is filled with a fluid such as a liquid or a gas. Organic contaminants, such as photoresist, photoresidue, and dry etched residue, occur in process steps of semiconductor fabrication and at times, require removal. The organic contaminants are removed from the semiconductor surface by holding the semiconductor inside a tank. The method is practiced using gas phase processing. The tank is filled with a gas mixture, comprising water vapor and ozone.
