    摘要: An improved semiconductor-on-insulator (SOI) substrate is provided, which contains a patterned buried insulator layer at varying depths. Specifically, the SOI substrate has a substantially planar upper surface and comprises: (1) first regions that do not contain any buried insulator, (2) second regions that contain first portions of the patterned buried insulator layer at a first depth (i.e., measured from the planar upper surface of the SOI substrate), and (3) third regions that contain second portions of the patterned buried insulator layer at a second depth, where the first depth is larger than the second depth. One or more field effect transistors (FETs) can be formed in the SOI substrate. For example, the FETs may comprise: channel regions in the first regions of the SOI substrate, source and drain regions in the second regions of the SOI substrate, and source/drain extension regions in the third regions of the SOI substrate.

    摘要: A silicon containing fin is formed on a semiconductor substrate. A silicon oxide layer is formed around the bottom of the silicon containing fin. A gate dielectric is formed on the silicon containing fin followed by formation of a gate electrode. While protecting the portion of the semiconductor fin around the channel, a bottom portion of the silicon containing semiconductor fin is etched by a isotropic etch leaving a body strap between the channel of a finFET on the silicon containing fin and an underlying semiconductor layer underneath the silicon oxide layer. The fin may comprise a stack of inhomogeneous layers in which a bottom layer is etched selectively to a top semiconductor layer. Alternatively, the fin may comprise a homogeneous semiconductor material and the silicon containing fin may be protected by dielectric films on the sidewalls and top surfaces of the silicon containing fin.

    摘要: A deep trench is formed in a semiconductor substrate. The deep trench may comprise a pair of parallel substantially vertical sidewalls having a constant separation distance. A set of outer substantially vertical sidewalls may have a closed shape in a horizontal cross-section. At least one dielectric layer is formed in the deep trench. The deep trench is filled with at least one conductive trench fill material to form a conductive deep trench fill region. A shallow trench isolation structure is formed directly on the deep trench to encapsulate the conductive deep trench fill region therebeneath. The stack of the deep trench and the shallow trench isolation structure form a deep trench inter-well isolation structure that provides electrical isolation of devices on one side of the stack from devices on the other side.

    摘要: A method of fabricating and a structure of an IC incorporating strained MOSFETs on separated silicon layers are disclosed. N-channel field effect transistors (nFET) and P-channel FETs (pFET) are formed on the separated silicon layers, respectively. Shallow trench insulation (STI) regions adjacent to the nFETs and pFETs thus can be formed to induce different stress to the channel regions of the respective nFETs and pFETs. As a consequence, performance of both the nFETs and the pFETs can be improved by the STI stress. In addition, the area of the IC can also be reduced as the two silicon layers are positioned vertically relative to one another.

    摘要: A gap fill nitride is formed in an underlapping region between a first semiconductor area with a first stress liner and a second semiconductor area with a second stress liner without plugging other tightly spaced structures. This is achieved by filling the tightly spaced structures with middle-of-line dielectric material such as silicon oxide in both the first and the second semiconductor areas prior to the formation of the gap fill nitride. The combination of the first and second stress liners and the gap fill nitride provides a continuous mobile ion diffusion barrier across the entire surface of a CMOS semiconductor structure.

    摘要: Multiple finFETs containing semiconductor fins with the same height for the top but with different heights for the bottom are formed. Patterned oxygen implant masks are used to form a buried oxide layer with at least two different levels of oxide top surface. After the formation of the buried oxide layer, the top semiconductor layer has a substantially level top surface. Fins are formed by lithographically patterning and etching the top semiconductor layer. The resulting fins may be semiconductor fins with different heights or fins comprising an upper portion of semiconductor fins and a lower portion of oxide fins. In both cases, semiconductor fins of different heights are used to form finFETs with fractional on-current of a full height finFET.
