Abstract: A method for forming a CMOS image sensor spacer structure. A polysilicon gate electrode is formed on a substrate; a thin layer of first dielectric is deposited over the exposed surfaces of the gate electrode and the top of the substrate. Next a second layer of dielectric is deposited after which etching is performed to create the electrode spacer. The deposited second layer of dielectric serves as an etch stop and prevents damage to the substrate surface between spacers of the gate electrodes. An alternate method uses a thin ply layer as the stop layer and, in so doing, source/drain damage caused by the white pixel problem.

Abstract: A method is provided for forming multi-layer spacer GELS) for flash EEPROM devices. A composite tetraethyl orthosilicate-silicon nitride (TEOS/Si.sub.3 N.sub.4) layer is deposited over the floating gate and anisotropically etched to form the MLS. The resulting MLS is better controlled dimensionally with the attendant advantage, therefore, of better definition of gate and channel lengths in the memory cell for more predictable and better programming and erase performance of EEPROMS.

Abstract: A high-sheet-resistance polysilicon resistor for integrated circuits is achieved by using a two-layer polysilicon process. After forming FET gate electrodes and capacitor bottom electrodes from a polycide layer, a thin interpolysilicon oxide (IPO) layer is deposited to form the capacitor interelectrode dielectric. A doped polysilicon layer and an undoped polysilicon layer are deposited and patterned to form the resistor. The doped polysilicon layer is in-situ doped to minimize the temperature and voltage coefficients of resistivity. Since the undoped polysilicon layer has a very high resistance (infinite), the resistance is predominantly determined by the doped polysilicon layer.

A blanket tunnel oxide layer covers the cap layer, the sidewalls of the floating gate electrode, and the exposed surfaces of the gate oxide layer. A spacer structure is formed on the surface of the tunnel oxide layer adjacent to the sidewalls of the floating gate electrode and above the gate oxide layer. A dielectric, silicon nitride inner spacer, having an annular or an L-shaped cross section, is formed on the blanket tunnel oxide layer adjacent to the sidewalls of the floating gate electrode. In the case of the L-shaped cross section inner spacer, an outer dielectric, spacer is formed over the inner dielectric, spacer. A blanket interelectrode dielectric layer covers the blanket tunnel oxide layer, and the spacer structure.

Abstract: A method for forming a tungsten plug is disclosed herein. A TiSi.sub.2 layer is selectively formed in a contact hole by using chemical vapor deposition. Then, a TiN layer is formed on the surface of the contact hole and on the TiSi.sub.2 layer. Next, a tungsten layer is formed on the TiN layer and in the contact hole. A CMP is used to remove a portion of the tungsten layer and TiN layer for planarization.

Abstract: A method is provided for forming nitride spacers for flash EEPROM devices. A silicon nitride layer is formed over the floating gate in a memory cell. Unlike in conventional methods where the nitride layer is usually subjected to anisotropic etching, it is disclosed in this invention that when partial isotropic/anisotropic etching of a particular recipe is performed, the resulting nitride spacers are better controlled dimensionally with the attendant advantage, therefore, of better definition of gate and channel lengths during subsequent implantations. In a second embodiment, the partial isotropic/anisotropic etching is followed by full anisotropic etching of another recipe with even better defined parameters for the flash EEPROMS.

Abstract: An improved frame involves two main principles which contribute to a superior bicycle frame. The first principle involves the use of a tear drop cross sectionally shaped down tube which is oriented with the small radius side facing forward and down. This orientation of the tube, for a given size of bicycle frame yields an unexpectedly high force to failure characteristic. In the case of a forward shock as by hitting a pothole, rock, or log, the resulting frame will be much more resistant to damage. Secondly, the preferred embodiment of the frame includes three sections, including a teardrop section, a transition section in which the teardrop shape transitions to a round shape, and a length of straight tube. The transition to a round shape, with or without a length of constant circular round shape adds rigidity to the bottom of the frame to provide provide increased lateral support.
