Abstract: An integrated circuit and method of fabricating integrated circuits is provided for an integrated circuit having threshold voltage adjustment. Unlike conventional methods and devices, threshold voltage adjustment is provided by an inert ion implantation process whereby inert ions are implanted into an underlying substrate. The implantation forms a semi-insulative layer comprised of an accumulation of inert ions. The inert ion region is formed between source and drain regions of a device on the integrated circuit. During operation of the device, the accumulation region confines the depth of the depletion layer. By confining the depth of the depletion layer, the threshold voltage of the device is reduced.

Abstract: An ultra-large scale integrated (ULSI) circuit includes MOSFETs which have a gate conductor with dopants distributed in a box-like distribution. The dopants also achieve high electrical activation. The MOSFETs utilize gate structures with heavily doped polysilicon material or heavily doped polysilicon and germanium material. The polysilicon and polysilicon and germanium materials are manufactured by utilizing amorphous semiconductor layers. Excimer laser annealing is utilized to activate the dopants and to provide a box-like dopant profile.

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.
