    摘要: A word line is buried beside a vertical semiconductor device. The word line is embedded adjacent to the vertical semiconductor device such that the topography of the word line is substantially planar. The planar features of the buried word line allows further processing to performed over the word line and the vertical transistor. In another embodiment, the vertical semiconductor device is a transistor having a vertically oriented gate. The word line is buried beside the vertically oriented gate, such that the topography of the word line is substantially planar.

    摘要: A random access memory cell having a trench capacitor formed below the surface of the substrate. A shallow trench isolation is provided to isolate the memory cell from other memory cells of a memory array. The shallow trench isolation includes a top surface raised above the substrate to reduce oxidation stress.

    摘要: A complementary metal oxide (CMOS) integrated circuit configured for reducing the formation of silicon defects in its silicon substrate during manufacture. The silicon defects are formed from silicon interstitials present in the silicon substrate. The CMOS integrated circuit includes a deep implantation region formed within the silicon substrate. There is further included at least one vertical trench formed in the silicon substrate. The trench is formed such that at least a portion of the trench penetrates into the deep implantation region of the silicon substrate to present vertical surfaces within the deep implantation region, thereby allowing the silicon interstitials to recombine at the vertical surfaces.

    摘要: Methods of manufacturing trench-bounded buried-channel p-type metal oxide semiconductor field effect transistors (p-MOSFETs), as used in dynamic random access memory (DRAM) technologies, for significantly reducing the anomalous buried-channel p-MOSFET sensitivity to device width. In one embodiment, the method comprises the initiation of a low temperature annealing step using an inert gas after the deep phosphorous n-well implant step, and prior to the boron buried-channel implant and 850°C gate oxidation steps. Alternatively, the annealing step may be performed after the boron buried-channel implant and prior to the 850°C gate oxidation step. In another embodiment, a rapid thermal oxidation (RTO) step is substituted for the 850°C gate oxidation step, following the deep phosphorous n-well and boron buried-channel implant steps. Alternatively, an 850°C gate oxidation step may follow the RTO gate oxidation step.
