摘要： A CVD method for forming a metal film on a substrate by using a metal carbonyl gas includes a preparing step for setting a vacuum chamber at a vacuum pressure and heating the substrate in the vacuum chamber to a first temperature where the metal carbonyl gas is decomposed. Also included are a supplying step for supplying the metal carbonyl gas into the vacuum chamber while exhausting the vacuum chamber with a first vacuum pumping speed and a removing step for removing a decomposed gas of the metal carbonyl gas by stopping supplying of the metal carbonyl gas and quickly exhausting the vacuum chamber with a second vacuum pumping speed sufficiently higher than the first vacuum pumping speed. The supplying step and the removing step can be repeatedly as desired.

摘要： A method of cleaning a powdery source supply system prevents outflow of particles from a chamber or an introduction line in a film forming process. A substrate processing system includes a powdery source supply system and a film forming processing unit. The powdery source supply system includes an ampoule for accommodating a powdery source, a carrier gas supply unit for supplying a carrier gas into the ampoule, an introduction line for connecting the ampoule and the film forming processing unit, a purge line branched from the introduction line, and a valve for opening or closing the introduction line. When the valve is opened and the interior of the purge line is evacuated prior to the film forming process, the carrier gas supply unit supplies a carrier gas so that the viscous force acting on particles by the carrier gas is greater than the viscous force in the film forming process.

摘要： A method for integrating a metal-containing film in a semiconductor device, for example a gate stack. In one embodiment, the method includes providing a substrate in a process chamber, depositing the tungsten-containing film on the substrate at a first substrate temperature by exposing the substrate to a deposition gas containing a tungsten carbonyl precursor, heat treating the tungsten-containing film at a second substrate temperature greater than the first substrate temperature to remove carbon monoxide gas from the tungsten-containing film, and forming a barrier layer on the heat treated tungsten-containing film. Examples of tungsten-containing films include W, WN, WSi, and WC. Additional embodiments include depositing metal-containing films containing Ni, Mo, Co, Rh, Re, Cr, or Ru from the corresponding metal carbonyl precursors.
