    摘要: A method of forming metal gate transistor includes providing a substrate; forming a gate dielectric layer, a work function metal layer and a polysilicon layer stacked on the substrate; forming a hard mask and a patterned photoresist on the polysilicon layer; 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 work function metal 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.

    摘要: It is intended to provide a plasma doping method and apparatus which are superior in the controllability of the concentration of an impurity that is introduced into a surface layer of a sample.A prescribed gas is introduced into a vacuum container 1 from a gas supply apparatus 2 while being exhausted by a turbomolecular pump 3 as an exhaust apparatus. The pressure in the vacuum container 1 is kept at a prescribed value by a pressure regulating valve 4. High-frequency electric power of 13.56 MHz is supplied from a high-frequency power source 5 to a coil 8 disposed close to a dielectric window 7 which is opposed to a sample electrode 6, whereby induction-coupled plasma is generated in the vacuum container 1. A high-frequency power source 10 for supplying high-frequency electric power to the sample electrode 6 is provided. Every time a prescribed number of samples have been processed, a dummy sample is subjected to plasma doping and then to heating. The conditions for processing of a sample are controlled so that the measurement value of the surface sheet resistance becomes equal to a prescribed value, whereby the controllability of the impurity concentration can be increased.
