    摘要: The invention provides a method of avoiding peeling on the wafer edge and the mark number. The method uses a design rule to expose the multi-layer on a wafer. The limit and the scope of the exposed distance are taken to ensure the polysilicon layers and the metal layers are covered by the dielectric layer after exposure. The polysilicon layers or the metal layers don't unclothe from the overlarge distance at the exposed dielectric layer, so the next structure formed on the exposed dielectric layer doesn't peeling from contacting with the polysilicon layer or the metal layer. The invention avoids to contaminate the wafer and the machine after the particles forming from peeling.

    摘要: An ion implantation method useful for fabricating shallow trench isolation structureimplants phosphorus ions instead of arsenic ions into a substrate when the source/drain regions of an NMOS device are doped. Alternatively, low energy ions are used in the ion implantation for forming the source/drain regions of an NMOS device. Consequently lattice dislocations of the crystal structure within a substrate is reduced and unwanted device leakage current is eliminated.

    摘要: The invention discloses a method of forming a finFET device. A hard mask layer is formed on an active area of a semiconductor substrate. A portion of the hard mask layer is etched to form a recess. A conformal gate defining layer is deposited on the recess and a tilt angle ion implantation process is performed. A part of the gate defining layer is removed to define a fin pattern. The fin pattern is subsequently transferred to the hard mask layer. The patterned hard mask layer having the fin pattern is utilized as an etching mask, and the semiconductor substrate is etched to form a fin structure.
