    摘要: A method for forming a high stress layer is provided. According to the method, a substrate is put into a reactor of a PECVD machine and a reaction gas is added into the reactor. Then, an assistant reaction gas which has the molecular weight greater than or equal to the molecular weight of nitrogen gas is added into the reactor. Next, a carrier gas which has the molecular weight smaller than the molecular weight of nitrogen gas is added into the reactor to increase the bombarding efficiency in film deposition. Thereby, the high stress layer is formed on the substrate.

    摘要: A method of forming a semiconductor device. The method comprises steps of providing a substrate having a first transistor, a second transistor and non-salicide device formed thereon and the conductive type of the first transistor is different from that of the second transistor. A buffer layer is formed over the substrate and a tensile material layer is formed over the buffer layer. A portion of the tensile material layer over the second transistor is thinned and a spike annealing process is performed. The tensile material layer is removed to expose the buffer layer over the substrate and a patterned salicide blocking layer is formed over the non-salicide device. A salicide process is performed for forming a salicide layer on a portion of the first transistor and the second transistor.

    摘要: A method of fabricating a shallow trench isolation structure is disclosed. On a substrate, a pad oxide layer and a mask layer are successively formed. The pad oxide layer, the mask layer and a portion of the substrate are patterned to form a trench. After performing a rapid wet thermal process, a liner layer is formed on the exposed surface of the substrate, including the exposed silicon surface of the substrate in the trench and sidewalls and the surface of the mask layer. An oxide layer is deposited over the trench and the substrate and fills the trench. A planarization process is performed until the mask layer is exposed. The mask layer and the pad oxide layer are removed to complete the shallow trench isolation structure.

    摘要: Methods of fabricating interconnect structures in a semiconductor integrated circuit (IC) are presented. A preferred embodiment comprises forming interconnect lines and vias through a dual-damascenes process. It includes forming a via dielectric layer, an etch stop layer directly over the via dielectric layer, and a trench dielectric layer over the etch stop layer. The etch stop layer is patterned through a first photolithography and etch process to form openings in the etch stop layer, prior to the formation of the trench dielectric layer. A second photolithography and etch process is performed after formation of the trench dielectric layer to create trench openings in the trench dielectric layer and via openings in the via dielectric layer, where the patterned etch stop layer acts as a hard-mask in forming vias in the via dielectric layer.
