    摘要: Methods of forming hyper-abrupt p-n junctions and design structures for an integrated circuit containing devices structures with hyper-abrupt p-n junctions. The hyper-abrupt p-n junction is defined in a SOI substrate by implanting a portion of a device layer to have one conductivity type and then implanting a portion of this doped region to have an opposite conductivity type. The counterdoping defines the hyper-abrupt p-n junction. A gate structure carried on a top surface of the device layer operates as a hard mask during the ion implantations to assist in defining a lateral boundary for the hyper-abrupt p-n junction.

    摘要: A method of forming a semiconductor device having two different strains therein is provided. The method includes forming a strain in a first region with a first straining film, and forming a second strain in a second region with a second straining film. Either of the first or second strains may be either tensile or compressive. Additionally the strains may be formed at right angles to one another and may be additionally formed in the same region. In particular a vertical tensile strain may be formed in a base and collector region of an NPN bipolar transistor and a horizontal compressive strain may be formed in the extrinsic base region of the NPN bipolar transistor. A PNP bipolar transistor may be formed with a compression strain in the base and collector region in the vertical direction and a tensile strain in the extrinsic base region in the horizontal direction.
