  • Publication number: 20130323916
    Abstract: A plasma doping apparatus which introduces a predetermined mass flow of gas from a gas supply device into a vacuum chamber while discharging the gas through an exhaust port by a turbo-molecular pump, which is an exhaust device in order to maintain the vacuum chamber under a predetermined pressure by a pressure adjusting valve. A high-frequency power source supplies high-frequency power of 13.56 MHz to a coil disposed in the vicinity of a dielectric window opposite a sample electrode in order to generate an inductively coupled plasma in the vacuum chamber. A sum of an area of an opening of a gas flow-off port opposed to a center portion of the sample electrode is configured to be smaller than that of an area of an opening of the gas flow-off port opposed to a peripheral portion of the sample electrode in order to improve the uniformity.

  • Patent number: 8492259
    Abstract: A method of forming metal gate structure includes providing a substrate; forming a gate dielectric layer, a material layer and a polysilicon layer stacked on the substrate; forming a first mask layer, a second mask layer and a patterned photoresist on the polysilicon layer; removing portions of the second mask layer and the first mask layer to form a hard mask by utilizing the patterned photoresist as an etching mask; removing the patterned photoresist, and next utilizing the hard mask as an etching mask to remove parts of the polysilicon layer and parts of the material layer. Thus, a gate stack is formed. Since the patterned photoresist is removed before forming the gate stack, the gate stack is protected from damages of the photoresist-removing process. The photoresist-removing process does not attack the sidewalls of the gate stack, so a bird's beak effect of the gate dielectric layer is prevent.

  • Publication number: 20120285818
    Abstract: In a plasma doping device according to the invention, a vacuum chamber is evacuated with a turbo-molecular pump as an exhaust device via a exhaust port while a predetermined gas is being introduced from a gas supply device in order to maintain the inside of the vacuum chamber to a predetermined pressure with a pressure regulating valve. A high-frequency power of 13.56 MHz is supplied by a high-frequency power source to a coil provided in the vicinity of a dielectric window opposed to a sample electrode to generate inductive-coupling plasma in the vacuum chamber. A high-frequency power source for supplying a high-frequency power to the sample electrode is provided. Uniformity of processing is enhanced by driving a gate shutter and covering a through gate.
