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.

摘要： A semiconductor device and method for forming the semiconductor device include forming structures in a semiconductor substrate. The structures have two or more different spacings between them. A dielectric material is deposited in the spacings. Ion species are implanted to a depth in the dielectric material to change an etch rate of the dielectric material down to the depth. The dielectric material having the ion species is etched selective to the dielectric material below the depth such that a substantially uniform depth in the dielectric material is created across the at least two spacings.

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.

摘要： A method for forming an electrical device that includes forming a high-k gate dielectric layer over a semiconductor substrate that is patterned to separate a first portion of the high-k gate dielectric layer that is present on a first conductivity device region from a second portion of the high-k gate dielectric layer that is present on a second conductivity device region. A connecting gate conductor is formed on the first portion and the second portion of the high-k gate dielectric layer. The connecting gate conductor extends from the first conductivity device region over the isolation region to the second conductivity device region. One of the first conductivity device region and the second conductivity device region may then be exposed to an oxygen containing atmosphere. Exposure with the oxygen containing atmosphere modifies a threshold voltage of the semiconductor device that is exposed.

摘要： A transistor includes a semiconductor layer, and a gate dielectric is formed on the semiconductor layer. A gate conductor is formed on the gate dielectric and an active area is located in the semiconductor layer underneath the gate dielectric. The active area includes a graded dopant region that has a higher doping concentration near a top surface of the semiconductor layer and a lower doping concentration near a bottom surface of the semiconductor layer. This graded dopant region has a gradual decrease in the doping concentration. The transistor also includes source and drain regions that are adjacent to the active region. The source and drain regions and the active area have the same conductivity type.
