    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: FDSOI devices and methods for the fabrication thereof are provided. In one aspect, a method for fabricating a device includes the following steps. A wafer is provided having a substrate, a BOX and a SOI layer. A hardmask layer is deposited over the SOI layer. A photoresist layer is deposited over the hardmask layer and patterned into groups of segments. A tilted implant is performed to damage all but those portions of the hardmask layer covered or shadowed by the segments. Portions of the hardmask layer damaged by the implant are removed. A first etch is performed through the hardmask layer to form a deep trench in the SOI layer, the BOX and at least a portion of the substrate. The hardmask layer is patterned using the patterned photoresist layer. A second etch is performed through the hardmask layer to form shallow trenches in the SOI layer.
