    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 present invention provides a method to make a local interconnect in an embedded memory. The method first involves defining both a memory array area and a periphery circuit area on the surface of a semiconductor wafer. Then, a plurality of gates and lightly doped drains (LDD) are separately formed in the memory array area and in the periphery circuit area. A silicon nitride layer and a dielectric layer are then formed, respectively, on the surface of the semiconductor wafer and on each gate. Next, a plurality of landing via holes and local interconnect holes are separately formed in the dielectric layer in the memory array area and in the periphery circuit area, followed by the filling of an electrical conducting layer in each hole to simultaneously form a landing via and local interconnect. Then, the dielectric layer and a portion of the silicon nitride layer in the periphery circuit area are removed to form a spacer on either side of each gate in the periphery circuit area. Finally, a silicide layer is formed on the top surface of the landing via in the memory array area, as well as on the surfaces of each gate and on the surface of the local interconnect in the periphery circuit area.

    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.
