Abstract: The present invention provides a system for dissipating any aberrant charge that may accumulate during the fabrication of a semiconductor device segment (200), obviating overstress or break down damage to a focal device structure (208) that might result from uncontrolled dissipation of the aberrant charge. A substrate (202) has first and second intermediate structures (204, 206) disposed atop the substrate, with the focal structure disposed atop the substrate therebetween. A first conductive structure (210) is disposed atop the second intermediate structure, the focal structure, and a portion of the first intermediate structure. A third intermediate structure (214) is disposed contiguously atop the first conductive structure and the first intermediate layer. A void (216) is formed in a peripheral region (218) of device segment, through the first and third intermediate layers down to the substrate.

Abstract: A process for manufacturing a Junction Field-Effect Transistor, comprises doping a semiconductor material formed on an insulating substrate with impurities of a first conductivity type to form a well region. The process continues by implanting impurities of a second conductivity type into said well region to form a channel region, and by implanting impurities of the first conductivity type in said well region to form a back gate region. The process continues by forming a trench to expose at least one sidewall of said channel region, wherein the trench extends far enough along the sidewall to expose at least a portion of said back gate region. The process continues by depositing polysilicon to fill said trench along the at least one sidewall of said channel region and at least a portion of said back gate region, wherein at least a portion of the polysilicon will form a gate contact. The polysilicon is then doped with impurities of a first conductivity type.

Abstract: A field effect transistor with a fin structure having a first and a second source/drain region; a body region formed within the fin structure and between the first and the second source/drain region; a metallically conductive region formed within a part of the first source/drain region, the metallically conductive region being adjacent to the body region or to a lightly doped region disposed between the body region and the first source/drain region; and a current ballasting region formed within a part of the second source/drain region.

Abstract: The disclosure herein pertains to fashioning an n channel junction field effect transistor (NJFET) and/or a p channel junction field effect transistor (PJFET) with an open drain, where the open drain allows the transistors to operate at higher voltages before experiencing gate leakage current. The open drain allows the voltage to be increased several fold without increasing the size of the transistors. Opening the drain essentially spreads equipotential lines of respective electric fields developed at the drains of the devices so that the local electric fields, and hence the impact ionization rates are reduced to redirect current below the surface of the transistors.

Abstract: Fabrication of two differently configured like-polarity insulated-gate field-effect transistors (40 or 42 and 240 or 242) entails introducing multiple body-material semiconductor dopants of the same conductivity type into a semiconductor body. Gate electrodes (74 or 94) are defined such that each body-material dopant reaches a maximum concentration below the channel surface depletion regions, below all gate-electrode material overlying the channel zones (64 or 84), and at a different depth than each other body-material dopant. The transistors are provided with source/drain zones (60 or 80) of opposite conductivity type to, and with halo pocket portions of the same conductivity type as, the body-material dopants. One pocket portion (100/102 or 104) extends along both source/drain zones of one of the transistors. Another pocket portion (244 or 246) extends largely along only one of the source/drain zones of the other transistor so that it is asymmetrical.

Abstract: Means and methods are provided for trench TMOS devices (41-10, 11, 12), comprising, providing a first semiconductor (53, 53?) of a first composition having an upper surface (541), with a body portion (54) proximate the upper surface (541), a drift portion (46, 83) spaced apart from the upper surface (541) and a trench (49, 49?) having sidewalls (493) extending from the upper surface (541) into the drift portion (46, 83). A second semiconductor (56) adapted to provide a higher mobility layer is applied on the trench sidewalls (493) where parts (78) of the body portion (54) are exposed. A dielectric (70) covers the higher mobility layer (56) and separates it from a control gate (72) in the trench (49, 49?). Source regions (68) formed in the body portion (54) proximate the upper surface (491) communicate with the higher mobility layer (56).

Abstract: A Junction Field-Effect transistor with no surface contact for the back gate and twice as much transconductance in the channel and with a higher switching speed is achieved by intentionally shorting the channel-well PN junction with the gate region. This is achieved by intentionally etching away field oxide outside the active area at least in the gate region so as to expose the sidewalls of the active area down to the channel-well PN junction or a buried gate which is in electrical contact with the well. Polysilicon is then deposited in the trench and doped heavily and an anneal step is used to drive impurities into the top and sidewalls of the channel region thereby creating a “wrap-around” gate region which reaches down the sidewalls of the channel region to the channel-well PN junction.

Abstract: A ferroelectric random access memory (FRAM) includes a semiconductor substrate and an interlayer insulating layer on the substrate. A diffusion preventive layer is on the interlayer insulating layer. The diffusion preventive layer and the interlayer insulating layer have two node contact holes formed therein. Node conductive layer patterns are aligned with the node contact holes, respectively, and are disposed so as to protrude upward from the diffusion preventive layer. Lower electrodes are disposed on the diffusion preventive layer that cover the node conductive layer patterns, respectively. Thicknesses of the lower electrodes are gradually reduced from a line extending from upper surfaces of the node conductive layer patterns toward the diffusion preventive layer.

Abstract: By forming MOSFETs on a substrate having pre-existing ridges of semiconductor material (i.e., a “corrugated substrate”), the resolution limitations associated with conventional semiconductor manufacturing processes can be overcome, and high-performance, low-power transistors can be reliably produced. Ridges on the corrugated substrate can be created using high precision techniques that are not ordinarily suitable for device production. MOSFETs that subsequently incorporate the high-precision ridges into their channel regions will typically exhibit much more precise and less variable performance than similar MOSFETs formed using optical lithography-based techniques that cannot provide the same degree of patterning accuracy.
