  • Publication number: 20050127435
    Abstract: A method of manufacturing a microelectronic device including, in one embodiment, providing a substrate having a plurality of partially completed microelectronic devices including at least one partially completed memory device and at least one partially completed transistor. At least a portion of the partially completed transistor is protected by forming a first layer over the portion of the partially completed transistor to be protected during a subsequent material removal step. A second layer is formed substantially covering the partially completed memory device and the partially completed transistor. Portions of the second layer are removed leaving a portion of the second layer over the partially completed memory device. At least a substantial portion of the first layer is removed from the partially completed transistor after the portions of the second layer are removed.

  • Patent number: 6849499
    Abstract: A method is provided for forming a flash memory cell having an amorphous silicon floating gate capped by a CVD oxide, and a control gate formed over an intergate oxide layer formed over the oxide cap. Amorphous silicon is first formed over a gate oxide layer over a substrate, followed by the forming of a silicon nitride layer over the amorphous silicon layer. Silicon nitride is patterned to have a tapered opening so that the process window for aligning the floating gate with the active region of the cell is achieved with a relatively wide margin. Next, an oxide cap is formed over the floating gate. Using an oxide deposition method in place of the conventional polyoxidation method provides a less bulbous oxide formation over the floating gate, thus, yielding improved erase speed for the cell. The invention is also directed to a flash memory cell fabricated by the disclosed method.

  • Patent number: 6828183
    Abstract: A process for forming a high voltage oxide (HV) and a select gate poly for a split-gate flash memory is disclosed. The general difficulty of forming oxides of two different thicknesses for two different areas on the same substrate is alleviated by forming an HV oxide layer over the entire substrate just prior to the forming of the control gate of a cell area after the forming of a gate oxide layer over the peripheral area of the substrate. At an immediate subsequent step, a peripheral gate is formed over the HV oxide over the peripheral area, and, as a final step, the forming of the control gate, or the select gate of the cell area follows next.

  • Patent number: 6819593
    Abstract: A method to suppress bit-line leakage in a nonvolatile memory cell is achieved. The method comprises providing an array of nonvolatile memory cells comprising source and bulk terminals. The array comprises a plurality of subarrays. The sources of all the nonvolatile cells in each subarray are coupled together to form a common subarray source. Bulks of all the nonvolatile cells in the array are coupled together to form a common array bulk. A first, non-zero voltage is forced between the common subarray source and the common array bulk for a first subarray that is selected for an access operation. A second, non-zero voltage is forced between the common subarray source and the common array bulk for a second subarray that is not selected for an access operation. The second, non-zero voltage inhibits bit line leakage in the second subarray.

  • Patent number: 6649489
    Abstract: A method of etch polysilicon adjacent to a recessed STI structure feature is described. A substrate is provided with a dielectric layer thereon and a polysilicon layer on the dielectric layer. A shallow trench is formed that extends through the polysilicon and dielectric layers into the substrate. An insulating material is used to fill the trench and is then recessed in the trench below the surface of the substrate by polishing and etching steps. A conformal buffer layer is deposited which covers the polysilicon and sidewalls of the trench above the recessed insulating layer. The buffer layer is etched back to expose the insulating layer and the polysilicon is removed by a plasma etch. A spacer comprised of a portion of the buffer layer protects the substrate during the polysilicon etch to prevent unwanted trenches from being formed adjacent to the STI structure, thereby increasing the etch process window.

  • Patent number: 6569736
    Abstract: A method for forming square polysilicon spacers on a split gate flash memory device by a multi-step polysilicon etch process is described. The method can be carried out by depositing a polysilicon layer on the flash memory device structure and then depositing a sacrificial layer, such as silicon oxide, on top of the polysilicon layer. The sacrificial layer has a slower etch rate than the polysilicon layer during a main etch step. The sacrificial layer overlies the flash memory device is then removed, while the sacrificial layer on the sidewall is kept intact. The polysilicon layer that overlies the flash memory device is then etched away followed by a step of removing all residual sacrificial layers. The exposed polysilicon layer is then etched to define the square polysilicon spacers on the split gate flash memory device.
