    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 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: A method of enhancing chemical mechanical polishing uniformity is provided. In the fabrication of a shallow trench isolation structure, there are active area regions with different integration formed in a chip. The integration of the active area regions in the chip is computed according circuit designs by a program analysis. One of the active area regions with the highest integration is used as a basis, dummy mesas are formed in the other active area regions to adjust the integration of the chip.
