    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 pedestal is formed out of the pad layer such that two edges of the pedestal coincide with a border of the wells as implanted. An extended pedestal is formed over the pedestal by depositing a conformal dielectric layer. The area of the extended pedestal is exposed the semiconductor surface below is recessed to a recess depth. Other trenches including at least one intra-well isolation trench are lithographically patterned. After a reactive ion etch, both an inter-well isolation trench and at least one intra-well isolation trench are formed. The width of the inter-well isolation trench may be reduced due to the deeper bottom surface compared to the prior art structures. The boundary between the p-well and the n-well below the inter-well isolation structure is self-aligned to the middle of the inter-well isolation 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.

    摘要: The present invention relates to high performance three-dimensional (3D) field effect transistors (FETs). Specifically, a 3D semiconductor structure having a bottom surface oriented along one of a first set of equivalent crystal planes and multiple additional surfaces oriented along a second, different set of equivalent crystal planes can be used to form a high performance 3D FET with carrier channels oriented along the second, different set of equivalent crystal planes. More importantly, such a 3D semiconductor structure can be readily formed over the same substrate with an additional 3D semiconductor structure having a bottom surface and multiple additional surfaces all oriented along the first set of equivalent crystal planes. The additional 3D semiconductor structure can be used to form an additional 3D FET, which is complementary to the above-described 3D FET and has carrier channels oriented along the first set of equivalent crystal planes.
