    摘要: A method of forming a semiconductor structure may include preparing a continuous active layer in a region of the substrate and forming a plurality of adjacent gates on the continuous active layer. A first raised epitaxial layer may be deposited on a recessed region of the continuous active layer between a first and a second one of the plurality of gates, whereby the first and second gates are adjacent. A second raised epitaxial layer may be deposited on another recessed region of the continuous active layer between the second and a third one of the plurality of gates, whereby the second and third gates are adjacent. Using a cut mask, a trench structure is etched into the second gate structure and a region underneath the second gate in the continuous active layer. The trench is filled with isolation material for electrically isolating the first and second raised epitaxial layers.

    摘要: A method of forming a semiconductor structure on a substrate is provided. The method may include preparing a continuous active layer on a region of the substrate and depositing a first raised epitaxial layer on a first region of the continuous active layer. A second raised epitaxial layer is also deposited on a second region of the continuous active layer such that the first raised epitaxial layer is in close proximity to the second raised epitaxial layer. A mask may be used to etch a trench structure into the continuous active layer at both the first and the second raised epitaxial layer, whereby the etched trench structure is filled with isolation material for electrically isolating the first raised epitaxial layer from the second raised epitaxial layer.

    摘要: A method for simultaneously forming a line interconnect such as a bitline and a borderless contact to diffusion, e.g. bitline contact, is described. A semiconductor substrate having prepatterned gate stacks thereon is covered with a first dielectric to form a first level and then a second dielectric is deposited which forms a second level. Line interconnect openings are defined in the second level by lithography and etching. Etching is continued down to monocrystalline regions in an array region of the substrate to form borderless contact openings coincident to the line interconnects between the gate stacks. The openings are filled with one or more conductors to form contacts to diffusion, e.g. bitline contacts, which are coincident to the line interconnects, e.g. bitlines.
