  • Patent number: 6866882
    Abstract: The vacuum degree in a reactor is set to as low as 0.1 Torr. In this state, a butyl acetate solution in which Pb(DPM)2 is dissolved at a concentration of 0.1 mol is transported from a Pb source generator to an evaporator, while the flow rate of the butyl acetate solution is controlled to a predetermined flow rate by a massflow controller, to evaporate the Pb(DPM)2 dissolved together with the butyl acetate by the evaporator. Helium gas is added to these at a flow rate of 250 sccm, and the mixed gas is transported to a shower head. With this operation, source gases are supplied to a wafer in the reactor, while the partial pressure of each source gas is set low.

  • Publication number: 20050016687
    Abstract: An insulating film consisting of first and second tantalum oxide layers is formed on a semiconductor wafer. First, an amorphous first layer is formed by CVD, and a reforming process for removing organic impurities contained in the first layer is carried out. Then, an amorphous second layer is formed by CVD on the first layer. Then, a reforming process for removing organic impurities contained in the second layer is carried out by supplying a process gas containing ozone into a process chamber while heating the wafer to a temperature lower than a crystallizing temperature over a certain period. Further, within the same process chamber, the wafer is successively heated to a second temperature higher than the crystallizing temperature, followed by cooling the wafer to a temperature lower than the crystallizing temperature so as to crystallize the first and second layers simultaneously.

  • Publication number: 20040053472
    Abstract: This method for film formation has a first step of forming a first insulation film, the essential component of which is a material having a first dielectric constant, on the surface of a semiconductor substrate and a second step of forming a second insulation film, the essential component of which is a material having a second dielectric constant larger than the first dielectric constant, on the first insulation film to be thicker than this first insulation film. Since the process of forming a film of a high dielectric constant material that constitutes the second insulation film is executed successively, following the formation of a barrier layer that is the first insulation film, it is possible to form a gate of a high dielectric constant material stable to the substrate.
