    摘要: A MOSFET device is formed on top of a semiconductor-on-insulator (SOI) substrate having a semiconductor layer with a thickness ranging from 3 nm to 20 nm. A stair-shape raised extension, a raised source region and a raised drain region (S/D) are formed on top of the SOI substrate. The thinner raised extension region abuts at a thin gate sidewall spacer, lowering the extension resistance without significantly increasing the parasitic resistance. A single epitaxial growth forms the thinner raised extension and the thicker raised S/D preferably simultaneously, reducing the fabrication cost as well as the contact resistance between the raised S/D and the extension. A method of forming the aforementioned MOSFET device is also provided.

    摘要: A method for fabricating an FET device characterized as being a tunnel FET (TFET) device is disclosed. The method includes processing a gate-stack, and processing the adjoining source and drain junctions, which are of a first conductivity type. A hardmask is formed covering the gate-stack and the junctions. A tilted angle ion implantation is performed which is received by a first portion of the hardmask, and it is not received by a second portion of the hardmask due to the shadowing of the gate-stack. The implanted portion of the hardmask is removed and one of the junctions is exposed. The junction is etched away, and a new junction, typically in-situ doped to a second conductivity type, is epitaxially grown into its place. A device characterized as being an asymmetrical TFET is also disclosed. The source and drain junctions of the TFET are of different conductivity types, and the TFET also includes spacer formations in a manner that the spacer formation on one side of the gate-stack is thinner than on the other side of the gate-stack.

The first epitaxy semiconductor material is located at a footprint of the at least one gate stack substantially within a pair of recessed regions in the substrate which are present on opposite sides of the at least one gate stack. A diffused extension region is located within an upper surface of said first epitaxy semiconductor material in each of the recessed regions. The structure further includes a second epitaxy semiconductor material located on an upper surface of the diffused extension region. The second epitaxy semiconductor material has a higher dopant concentration than the first epitaxy semiconductor material.

    摘要: A device and method for fabrication of fin devices for an integrated circuit includes forming fin structures in a semiconductor material of a semiconductor device wherein the semiconductor material is exposed on sidewalls of the fin structures. A donor material is epitaxially deposited on the exposed sidewalls of the fin structures. A condensation process is applied to move the donor material through the sidewalls into the semiconductor material such that accommodation of the donor material causes a strain in the semiconductor material of the fin structures. The donor material is removed, and a field effect transistor is formed from the fin structure.
