    摘要: An exemplary method of etching sacrificial layer includes steps of: providing a substrate formed with a sacrificial layer and defined with a first region and a second region, the sacrificial layer disposed in both the first and second regions; forming a hard mask covering the first region while exposing the second region; performing a first etching process on the sacrificial layer to thin the sacrificial layer while forming a byproduct film overlying the thinned sacrificial layer; performing a second etching process on the byproduct film to remove a portion of the byproduct layer for exposing a portion of the thinned sacrificial layer, while another portion of the byproduct film disposed on sidewalls of the thinned sacrificial layer being remained; and performing a third etching process on the thinned sacrificial layer, to remove the portion of the thinned sacrificial layer exposed in the second etching process.

    摘要: A method of fabricating a CMOS device having high-k dielectric layer and metal gate electrode is provided. First, an isolation structure is formed in a substrate to define a first-type and a second-type MOS regions; an interfacial layer and a high-k dielectric layer are sequentially formed over the substrate; a first and a second cover layers are respectively formed over a portion of the high-k dielectric layer at the first-type MOS region and another portion of the high-k dielectric layer at the second-type MOS region; afterwards, an in-situ etching step is performed to sequentially etch the first and second cover layers using a first etching solution and to etch both the high-k dielectric layer and the interfacial layer using a second etching solution until the substrate is exposed. Wherein, the second etching solution is a mixed etching solution containing the first etching solution.

    摘要: A method for removing a photoresist is disclosed. First, a substrate including a patterned photoresist is provided. Second, an ion implantation is carried out on the substrate. Then, a non-oxidative pre-treatment is carried out on the substrate. The non-oxidative pre-treatment provides hydrogen, a carrier gas and plasma. Later, a photoresist-stripping step is carried out so that the photoresist can be completely removed.
