    摘要: A method for removing silicon dioxide residuals is disclosed. The method includes reacting a portion of a silicon dioxide layer (i.e., oxide) to form a reaction product layer, removing the reaction product layer and annealing in an environment to remove oxide residuals. The method finds application in a variety of semiconductor fabrication processes including, for example, fabrication of a vertical HBT or silicon-to-silicon interface without an oxide interface.

    摘要: A method of fabricating a semiconductor structure. The method includes forming a first feature of a first active device and a second feature of a second active device, introducing a first amount of nitrogen into the first feature of the first active device, and introducing a second amount of nitrogen into the second feature of the second active device, the second amount of nitrogen being different from the first amount of nitrogen.

    摘要: A semiconductor structure includes thin gate dielectrics that have been selectively nitrogen enriched. The amount of nitrogen introduced is sufficient to reduce or prevent gate leakage and dopant penetration, without appreciably degrading device performance. A lower concentration of nitrogen is introduced into pFET gate dielectrics than into nFET gate dielectrics. Nitridation may be accomplished selectively by various techniques, including rapid thermal nitridation (RTN), furnace nitridation, remote plasma nitridation (RPN), decoupled plasma nitridation (DPN), well implantation and/or polysilicon implantation.
