    摘要: The present disclosure provides a method for making a semiconductor device. The method includes forming a first material layer on substrate; forming a patterned photoresist layer on the first material layer; applying an etching process to the first material layer using the patterned photoresist layer as a mask; and applying a nitrogen-containing plasma to the substrate to remove the patterned photoresist layer.

    摘要: The present disclosure provides a method for making metal gate stacks of a semiconductor device. The method includes applying a first dry etching process to a semiconductor substrate in an etch chamber through openings of a patterned mask layer defining gate regions, removing a polysilicon layer and a metal gate layer on the semiconductor substrate; applying a H2O steam to the semiconductor substrate in the etch chamber, removing a capping layer on the semiconductor substrate; applying a second dry etching process to the semiconductor substrate in the etch chamber, removing a high k dielectric material layer; and applying a wet etching process to the semiconductor substrate to remove polymeric residue.

    摘要: A method for cleaning semiconductor substrates includes a DI water clean operation that uses a spin speed no greater than 350 rpm. The cleaning method may include additional cleaning operations such as an organic clean, an aqueous chemical clean or a DI water/ozone clean. The cleaning method may be used to clean substrates after the conclusion of an etching procedure which exposes a single film between a Cu-containing conductive material and the environment. The spin speed of the DI water clean operation prevents copper corrosion due to breakdown of the film that separates the Cu-containing conductive material from the environment.
