  • Patent number: 7521314
    Abstract: A method for forming a semiconductor device includes forming a liner over a semiconductor material including a control electrode. The method further includes forming a first spacer adjacent to the control electrode, wherein the first spacer has a first width. The method further includes implanting current electrode dopants. The method further includes removing the first spacer. The method further includes forming a second spacer adjacent the control electrode, wherein the second spacer has a second width and wherein the second width is less than the first width. The method further includes using the second spacer as a protective mask to selectively remove the liner. The method further includes forming a stressor layer overlying the control electrode and current electrode regions.

  • Patent number: 6686633
    Abstract: A semiconductor device includes a memory array of static-random-access memory cells. The SRAM cells are formed using a process flow more closely associated with logic-type devices. The SRAM cells are formed using one semiconductor layer compared to at least three typically seen with SRAM cells. The SRAM cells include many features that allow its dimensions to be scaled to very small dimensions (less than 0.25 microns and possible down to 0.1 microns or even smaller). A unique process integration scheme allows formation of local interconnects (522 and 524), wherein each local interconnect (522, 524) cross couples the inverters of the SRAM and is formed within a single opening (70). Also, interconnect portions (104) of word lines are laterally offset from silicon portions (36) of the same word line, so that the interconnect portions do not interfere with bit line connections.

  • Patent number: 4915779
    Abstract: A residue-free plasma etch of high temperature aluminum copper metallization is provided by the use of a single plasma etcher. The metallization layer is covered by a protective oxide layer. This structure is then placed in the single etcher and a vacuum is established. The protective oxide layer is then etched and without breaking the vacuum or removing the structure from the etcher the metal layer is also etched. This results in the etched surface being residue-free.

  • Patent number: 4791073
    Abstract: A method is described for forming dielectric filled isolation trenches in semiconductor substrates in which a differentially etchable etch-stop layer is provided above the surface of the substrate during the trench filling process so that the height of the trench filling relative to the surface of the substrate may be adjusted for optimum overall results during subsequent fabrication steps and so that the substrate surface may be protected from contact with the etching reagents used during planarization of the trench filling material. This avoids damage to the substrate surface and permits improved surface planarity.

  • Patent number: 4717446
    Abstract: A method of detecting the endpoint of expitaxially grown silicon using a monitor wafer is described. A monitor wafer having a substrate, an oxide layer, and a polysilicon layer is process in an epi chamber along with working wafers. The monitor wafer is used to determine the endpoint of the working wafers epi layer when the epi layer is etched.
