    摘要: A method of manufacturing a metal-oxide-semiconductor transistor device is disclosed. In the method, a silicon nitride spacer is formed and will be removed after an ion implantation process used to form a source/drain region and a salicide process used to form a metal silicide layer on the surface of the source/drain region and the gate electrode. The metal silicide layer is formed to comprise silicon (Si), nickel (Ni) and at least one metal selected from a group consisting of iridium (Ir), iron (Fe), cobalt (Co), platinum (Pt), palladium (Pd), molybdenum (Mo), and tantalum (Ta); therefore, when the silicon nitride spacer is removed by etching, the metal silicide layer is not damaged.

    摘要: A method for avoiding resist poisoning during a damascene process is disclosed. A semiconductor substrate is provided with a low-k dielectric layer (k≦2.9) thereon, a SiC layer over the low-k dielectric layer, and a blocking layer over the SiC layer. The blocking layer is used to prevent unpolymerized precursors diffused out from the low-k dielectric layer from contacting an overlying resist. A bottom anti-reflection coating (BARC) layer is formed on the blocking layer. A resist layer is formed on the BARC layer, the resist layer having an opening to expose a portion of the BARC layer. A damascene structure is formed in the low-k dielectric layer by etching the BARC layer, the blocking layer, the SiC layer, and the low-k dielectric layer through the opening.

    摘要: A method of stripping photoresist is provided. First, a first dielectric layer including a plurality of contact structures is provided. Then, a barrier layer is formed over the first dielectric layer. Thereafter, a second dielectric layer is formed over the barrier layer. Next, a patterned photoresist layer is formed over the second dielectric layer. Then, the patterned photoresist layer is used as a mask layer for patterning the second dielectric layer and the barrier layer to expose a portion of the contact structures. Furthermore, the patterned photoresist layer is removed by using an oxygen-free reducing gas. Since the reducing gas does not contain oxygen, the process can prevent oxide from forming on the contact structures, thereby reducing resistance of the contact structures.

    摘要: A two-step stripping method for removing via photoresist during the fabrication of trench-first partial-via dual damascene features is disclosed. In the first cleaning step, inert gas (He, Ar, N2)/fluorocarbon plasma is used to contact the remaining “Via Photo” for a short time period not exceeding 20 seconds. Thereafter, in the second cleaning step, a reducing plasma is used to completely strip the remaining “Via Photo”, thereby preventing the low-k or ultra low-k carbon-containing dielectric layer from potential carbon depletion.

    摘要: A method for forming a metal oxide semiconductor (MOS) transistor is provided. First, a gate structure is formed over a substrate. Then, offset spacers are formed on respective sidewalls of the gate structure. A first ion implantation process is performed to form a lightly doped drain (LDD) in the substrate beside the gate structure. Other spacers are formed on respective sidewalls of the offset spacers. Thereafter, a second ion implantation process is performed to form source/drain region in the substrate beside the spacers. Then, a metal silicide layer is formed on the surface of the source and the drain. An oxide layer is formed on the surface of the metal silicide layer. The spacers are removed and an etching stop layer is formed on the substrate. With the oxide layer over the metal silicide layer, the solvent for removing the spacers is prevented from damaging the metal silicide layer.
