Abstract: A field effect transistor is fabricated to have a drain overlap and a source overlap to minimize series resistance between the gate and the drain and between the gate and the source of the field effect transistor. The parasitic Miller capacitance formed by the drain overlap and the source overlap is reduced by forming a depletion region at the sidewalls of the gate structure of the field effect transistor. The depletion region at the sidewalls of the gate structure is formed by counter-doping the sidewalls of the gate structure. The sidewalls of the gate structure at the drain side and the source side of the field effect transistor are doped with a type of dopant that is opposite to the type of dopant within the gate structure. Such dopant at the sidewalls of the gate structure forms a respective depletion region from the sidewall into approximately the edge of the drain overlap and source overlap that extends under the gate structure to reduce the parasitic Miller capacitance formed by the drain overlap and the source overlap.

Abstract: An improved semiconductor device, such as a MOSFET with raised source/drain extensions on a substrate with isolation trenches etched into the surface of the substrate . The device has thin first dielectric spacers on the side of a gate and gate oxide and extend from the top of the gate to the surface of the substrate. Raised source/drain extensions are placed on the surface of a substrate, which extend from the first dielectric spacers to the isolation trenches. Thicker second dielectric spacers are placed adjacent to the first dielectric spacers and extend from the top of the first dielectric spacers to the raised source/drain extensions. Raised source/drain regions are placed on the raised source/drain extensions, and extend from the isolation trenches to the second dielectric spacers. The semiconductor device has very shallow source drain extensions which result in a reduced short channel effect.

Abstract: A MOSBJT (Metal Oxide Semiconductor Bipolar Junction Transistor) is formed to have both the higher current drive capability of the BJT and the smaller device area of the scaled down MOSFET. The MOSBJT includes a collector region and an emitter region comprised of a semiconductor material with a first type of dopant. A base region is disposed between the collector region and the emitter region, and the base region is comprised of a semiconductor material with a second type of dopant that is opposite of the first type of dopant. Unlike a conventional BJT, a base terminal of the MOSBJT is comprised of a dielectric structure disposed over the base region and comprised of a gate structure disposed over the dielectric structure. Unlike a conventional MOSFET, the dielectric structure of the MOSBJT is relatively thin such that a tunneling current through the dielectric structure results when a turn-on voltage is applied on the gate structure. This tunneling current is a base current of the MOSBJT. Furthermore, unlike a conventional MOSFET, the dielectric structure and the gate structure of the MOSBJT are not disposed over the collector region and the emitter region to prevent tunneling current between the gate structure and the collector and emitter regions.

Abstract: For fabricating a field effect transistor having a gate structure on a gate dielectric within an active device area of a semiconductor substrate, a hardmask dielectric material covers a top surface of the gate structure. A drain silicide is formed with a drain contact junction that is exposed, and a source silicide is formed with a source contact junction that is exposed. The drain silicide and the source silicide have a first thickness and are comprised of a first silicide material. The hardmask dielectric material that covers the top surface of the gate structure prevents formation of silicide with the gate structure during formation of the drain silicide and the source silicide. An encapsulating dielectric material is then deposited to cover the drain silicide and the source silicide using a low temperature of less than about 400° Celsius. The hardmask dielectric material is etched away from the top surface of the gate structure to expose the top surface of the gate structure. A gate silicide is formed with the gate structure, and the gate silicide has a second thickness and is comprised of a second silicide material. The encapsulating dielectric material covering the drain silicide and the source silicide prevents further formation of the drain silicide and the source silicide during formation of the gate silicide. The present invention may be used to particular advantage when the first thickness of the drain and source suicides is less than the second thickness of the gate silicide and when the first silicide material of the drain and source silicides is different from the second silicide material of the gate silicide.

Abstract: For fabricating a field effect transistor on a buried insulating material in SOI (semiconductor on insulator) technology, a dielectric island is formed on the buried insulating material. An opening is etched through the buried insulating material at a location away from the dielectric island. An amorphous semiconductor material is deposited to fill the opening through the buried insulating material and to surround the dielectric island. The amorphous semiconductor material is polished until the top surface of the dielectric island is exposed and such that the amorphous semiconductor material surrounds the dielectric island. A layer of the amorphous semiconductor material is deposited on top of the dielectric island and on top of the amorphous semiconductor material surrounding the dielectric island. The amorphous semiconductor material surrounding the dielectric island and the layer of the amorphous semiconductor material are recrystallized to form a substantially single crystal structure of semiconductor material. A gate dielectric and a gate electrode of the field effect transistor are formed on top of a thinner portion of the semiconductor material disposed on the dielectric island. A drain extension region and a source extension region are formed by implanting a drain and source dopant into exposed regions of the thinner portion of the semiconductor material disposed on the dielectric island to minimize short channel effects. A drain contact region and a source contact region are formed from a thicker portion of the semiconductor material disposed to the sides of the dielectric island. The drain and source silicides are formed with the thicker drain and source contact regions to minimize parasitic resistance at the drain and source.
