    摘要: In the course of forming a trench capacitor or similar structure, the sidewalls of an aperture in a substrate are lined with a film stack containing a diffusion barrier; an upper portion of the outer layer is stripped, so that the upper and lower portions have different materials exposed; the lower portion of the film stack is stripped while the upper portion is protected by a hardmask layer; a diffusion step is performed in the lower portion while the upper portion is protected; and a selected material such as hemispherical grained silicon is deposited selectively on the lower portion while the exposed surface of the upper portion is a material on which the selected material forms poorly, so that the diffusing material penetrates and the selected material is formed only on the lower portion.

    摘要: An improved pitcher-shaped active area for a field effect transistor that, for a given gate length, achieves an increase in transistor on-current, a decrease in transistor serial resistance, and a decrease in contact resistance. The pitcher-shaped active area structure includes at least two shallow trench insulator (STI) structures formed into a substrate that defines an active area structure, which includes a widened top portion with a larger width than a bottom portion. An improved fabrication method for forming the improved pitcher-shaped active area is also described that implements a step to form STI structure divots followed by a step to migrate substrate material into at least portions of the divots, thereby forming a widened top portion of the active area structure. The fabrication method of present invention forms the pitcher-shaped active area without the use of lithography, and therefore, is not limited by the smallest ground rules of lithography tooling.

    摘要: An integrated circuit includes memory cells having array transistors separated by minimum lithographic feature size, and unsilicided metal bit lines encapsulated by a diffusion barrier while high performance logic transistors may be formed on the same chip without compromise of performance including an effective channel silicided contacts for low source/drain contact resistance, extension and halo implants for control of short channel effects and a dual work function semiconductor gate having a high impurity concentration and correspondingly thin depletion layer thickness commensurate with state of the art gate dielectric thickness. This structure is achieved by of an easily planarized material, and using a similar mask planarized to the height of the structures of differing materials to decouple substrate and gate implantations in the logic transistors.

    摘要: A gate structure for a semiconductor device, and particularly a MOSFET for such applications as CMOS technology. The gate structure entails an electrical insulating layer on a semiconductor substrate, over which a polysilicon gate electrode is formed. The gate structure further includes a gate conductor that is electrically connected with the gate electrode through a diffusion barrier layer having semi-insulating properties. The composition and thickness of the diffusion barrier layer are tailored so that the barrier layer is effective to block diffusion and intermixing between the gate conductor and polysilicon gate electrode, yet provides sufficient capacitive coupling and/or current leakage so as not to significantly increase the gate propagation delay of the gate structure.

This structure is achieved by development of thick/tall structures of differing materials using a mask or anti-spacer, preferably of an easily planarized material, and using a similar mask planarized to the height of the structures of differing materials to decouple substrate and gate implantations in the logic transistors.
