    Abstract: Submicron-dimensioned MOS and/or CMOS transistors are fabricated utilizing a simplified removable sidewall spacer technique, enabling effective tailoring of individual transistors to optimize their respective functionality. Embodiments include forming a first sidewall spacer having a first thickness on the side surfaces of a plurality of gate electrodes of transistors, selectively removing the first sidewall spacers from the gate electrodes of certain transistors, and then depositing second sidewall spacers on remaining first sidewall spacers and on the side surfaces of the gate electrodes from which the first sidewall spacers have been removed. Embodiments enable separately tailoring n- and p-MOS transistors as well as individual n- or p-MOS transistors having different functionality, e.g., different drive current and voltage leakage requirements.

    Abstract: A method and apparatus for reducing band-to-band currents during the erasure of a flash EEPROM memory cell is provided. The apparatus has a back biasing connection on the substrate at which a biasing voltage is applied during erasure of the flash EEPROM memory cell. The method of applying the biasing voltage to the back biasing connection during erasure of the flash EEPROM memory cell reduces band-to-band current between the source region and the substrate during erasure of the flash memory cell. This reduction provides for gate size reduction in flash memory cells without inducing detrimental short channel effects.

    Abstract: A method of fabricating an interconnection level of conductive lines and connecting vias separated by insulation for integrated circuits and substrate carriers for semiconductor devices using a reverse damascene in the formation of the conductive lines and vias. A conductive line pattern is first used to etch completely through the layer to form conductive line openings. The openings are completely filled with a conductive material and planarized so that the surfaces of the conductive material and the insulating layer are coplanar. A via pattern is aligned perpendicular to the conductive lines and the conductive material is etched half way through the conductive lines in other than the areas covered by the via pattern. The openings thus created in the upper portion of the conductive lines are filled with insulating material to complete the dual damascene interconnection level with the conductive lines in the lower portion of the insulating layer and upwardly projecting vias in the upper portion of the layer. In addition, a triple damascene layer is formed by starting with an insulating layer about one-third thicker than normal and by combining the standard dual damascene method with the above described method. The resulting interconnection level structure comprises conductive lines having upwardly and downwardly projecting vias.

    Abstract: A dual damascene method of fabricating an interconnection level of conductive lines and connecting vias separated by insulation for integrated circuits and substrate carriers for semiconductor devices using a thin protective via mask to form the via openings. A conductive line mask pattern is used to form conductive line openings in an insulating layer. Next, a thin protective layer of conformal material is deposited in the conducive line opening. The protective layer and the insulating layer each have etch resistance to others etchant. Using a via mask pattern, openings are etching the protective layer with the insulating layer serving as and etch stop. Next via openings are etched in the insulating material using the openings in the thin protective layer as the etch mask. If the protective layer is a conductive material, it is removed from the surface of the insulating layer either before or after the conductive line and via openings are filled with a conductive material. If the protective material is an insulating material, it is entirely removed before filling the conductive line and via openings conductive material.

    Abstract: A method for constraining lateral growth of gate caps formed during an epitaxial silicon growth process to achieve raised source/drain regions on poly silicon is presented. The method is appropriate for integration into a manufacturing process for integrated circuit semiconductor devices. The method utilizes selective etch processes, dependant upon the material comprising the protective layer (hard mask) over the gate and the material of the spacers, e.g., oxide mask/nitride spacers, or nitride mask/oxide spacers.
