    Abstract: A method for manufacturing a PMOS transistor. A gate terminal is formed over a substrate. Spacers are formed on the sidewalls of the gate terminal. A source/drain terminal is formed in the substrate on each side of the gate terminal, and then a metal silicide layer is formed over the top surface of the gate terminal and the substrate. The spacers are next removed. Using the metal silicide layer as a mask, a source/drain extension region is formed in the substrate between the gate terminal and the source/drain terminal. Similarly, using the metal silicide layer as a mask, an anti-punchthrough region is form in the substrate interior under the source/drain extension region.

    Abstract: A method for forming a semiconductor device is disclosed. The method includes providing a semiconductor substrate, followed by forming a gate oxide layer and a conductive layer over the substrate. An anti-reflective coating is then formed on the conductive layer. After patterning to etch the anti-reflective coating and the conductive layer, a gate region is thus formed. A dielectric layer is formed over the gate region, and is then subjected to etching back, therefore forming an offset spacer on sidewall of the gate region while simultaneously removing surface oxide of the anti-reflective coating. Finally, anti-reflective coating is removed.

    Abstract: The present invention discloses a method to manufacture a self-aligned silicide layer on a substrate. A metal oxide semiconductor (MOS) device and a shallow trench are fabricated in the substrate. The device has a gate structure, spacers of the gate structured and doping regions. The shallow trench is refilled with silicon oxide material for isolation. A silicon layer is nonconformally deposited on the top surface of the gate structure, the spacers and the doping regions by using a physical vapor deposition (PVD) process, such as ion metal plasma (IMP) process. The IMP process, like a sputtering process, is to ionize a silicon material or a refractory-metal material to silicon ions or metal ions and the ions are biased to anisotropically deposit on the top surface of the substrate. A refractory metal layer is defined on the top surface of the silicon layer by the IMP technology. A two-step thermal annealing process, such as rapid thermal annealing (RTA) process is performed to convert the silicon layer and the refractory metal layer into a silicide layer. Since the silicon layer serves as a silicon source for the salicide process, the silicide layer can form on the spacers and the silicon oxide material of the trench.

    Abstract: A method of forming a shallow trench isolation structure includes etching a substrate to form a trench. Then, an oxide layer is deposited in the trench and over the substrate by using high-density plasma. The oxide layer is pointed since it is formed by high-density plasma chemical vapor deposition. A stop layer made of silicon nitride, silicon oxy-nitride or boron nitride is formed on the oxide layer. The hardness of the stop layer is higher than that of the oxide layer so the protuberance of the oxide layer will be first removed during chemical mechanical polishing.

    Abstract: Salicide (self-aligned silicide) structures are formed using a process that does not form oxide spacer structures alongside polysilicon gate electrodes and wiring lines. A shaped polysilicon electrode is formed having protrusions extending beyond the sidewalls of the electrode. LDD source/drain regions are formed by ion implantation using only the polysilicon gate electrode as a mask, thereby forming LDD source drain/regions without using spacer oxide regions. Physical vapor deposition is used to deposit a metal layer having discontinuities at or adjacent the protrusions. A first rapid thermal anneal is performed to cause the metal to form a metal silicide over the polysilicon electrode. Unreacted metal is etched and then a second rapid thermal anneal is performed to convert the metal silicide to its lowest resistivity phase. Gate electrodes and wiring lines having this structure generally are formed having lower stress in the silicide layers, producing salicide structures having lower resistance than gate electrodes and wiring lines formed using conventional salicide techniques.

    Abstract: A method of making a self-aligned silicide which has an impurity diffusion region in a lower part of the source/drain regions adjacent to the isolating region. The method includes performing an ion implantation operation at a large tilt angle, which increases the junction depth of the source/drain regions and prevents the metallic silicide lying at the edge of the isolating region from getting too close to the source/drain junction and causing unwanted current leakages. The isolating regions are overetched, which exposes the surface of the source/drain regions. The metal silicide layer can thus be formed over the exposed source/drain surfaces, resulting in more surface area for the formation of a wide border contact window, resulting in a lowering of both contact resistance and sheet resistance there.
