    摘要: A method and an apparatus for fabricating a high tensile stress film includes providing a substrate, forming a poly stressor on the substrate, and performing an ultra violet rapid thermal process (UVRTP) for curing the poly stressor and adjusting its tensile stress status, thus the poly stressor serves as a high tensile stress film. Due to a combination of energy from photons and heat, the tensile stress status of the high tensile stress film is adjusted in a relatively shorter process period or under a relatively lower temperature.

    摘要: A method for forming a gate and a method for etching a conductive layer are provided. First, a substrate is provided, including a dielectric layer and a conductive layer on its surface in order. Subsequently, a patterned silicon nitride layer is formed on the conductive layer as a hard mask, and the hydrogen concentration of the patterned silicon nitride layer is more than 1022 atoms/cm3. Thereafter, the conductive layer and the dielectric layer are etched utilizing the hard mask as a mask. Finally, an etching solution is utilized to remove the hard mask.

    摘要: A method for fabricating a metal-oxide semiconductor (MOS) transistor is disclosed. The method includes the steps of: providing a semiconductor substrate; forming a gate structure on the semiconductor substrate and a source/drain region in the semiconductor substrate adjacent to two sides of the gate structure; covering a stress layer on the gate structure and the source/drain region; etching away the stress layer to form a plurality of openings with larger top and smaller bottom to expose surface of the gate structure and the source/drain region; forming a metal layer in the openings; and using the stress layer as a salicide block to react the metal layer with the gate structure and the source/drain region for forming a plurality of silicide layers.
