    Abstract: Vertical field effect transistors having a channel region defined by at least one semiconducting nanotube and methods for fabricating such vertical field effect transistors by chemical vapor deposition using a spacer-defined channel. Each nanotube is grown by chemical vapor deposition catalyzed by a catalyst pad positioned at the base of a high-aspect-ratio passage defined between a spacer and a gate electrode. Each nanotube grows in the passage with a vertical orientation constrained by the confining presence of the spacer. A gap may be provided in the base of the spacer remote from the mouth of the passage. Reactants flowing through the gap to the catalyst pad participate in nanotube growth.

    Abstract: A WRAPPED-GATE TRANSISTOR INCLUDES A SUBSTRATE HAVING AN UPPER SURFACE AND FIRST AND SECOND SIDE SURFACES OPPOSING TO EACH OTHER.SOURCE AND DRAIN REGIONS (28) ARE FORMED IN THE SUBSTRATE WITH A CHANNEL REGION THEREBETWEEN. THE CHANNEL REGION EXTENDS FROM THE FIRST SIDE SURFACE TO THE SECOND SIDE SURFACES OF THE SUBSTRATE. A GATE DIELECTRIC LAYER (40) IS FORMED ON THE SUBSTRATE. A GATE ELECTRODE (42) IS FORMED ON THE GATE DIELECTRIC LAYER TO COVER THE CHANNEL REGION FROM THE UPPER SURFACE AND THE FIRST AND SECOND SIDE SURFACES WITH THE GATE DIELECTRIC THEREBETWEEN. THE SUBSTRATE IS A SILICON ISLAND FORMED ON AN INSULATION LAYER OF AN SOI (SILICON-ON-INSULATOR) SUBSTRATE OR ON A CONVENTIONAL NON-SOI SUBSTRATE, AND HAS FOUR SIDE SURFACES INCLUDING THE FIRST AND SECOND SIDE SURFACES. THE SOURCE AND DRAIN REGIONS ARE FORMED ON THE PORTIONS OF THE SUBSTRATE ADJOINING THE THIRD AND FOURTH SIDE SURFACES WHICH ARE PERPENDICULAR TO THE FIRST AND SECOND SIDE SURFACES. THE WRAPPEDGATE STRUCTURE PROVIDES A BETTER AND QUICKER POTENTIAL CONTROL WITHIN THE CHANNEL AREA, WHICH YIELDS STEEP SUB-THRESHOLD SLOPE AND LOW SENSITIVITY TO THE "BODY-TO-SOURCE" VOLTAGE.(FIG 18A)

    Abstract: A METHOD FOR FORMING CONTACTS ON AN INTEGRATED CIRCUIT THAT ARE SELF-ALIGNED WITH THE WIRING PATTERNS OF THE INTEGRATED CIRCUIT. IN THE METHOD A THICKER LOWER LAYER (12) OF A FIRST MATERIAL AND A THINNER UPPER LAYER (14) OF A SECOND MATERIAL ARE FORMED ON A SUBSTRATE (10). THE FEATURES OF THE METAL WIRING IS PATTERNED FIRST ON THE UPPER LAYER. THE WIRING PATTERN TRENCHES (20) ARE ETCHED THROUGH THE THINNER SURFACE LAYER, AND PARTIALLY THROUGH THE SECOND, THICKER LAYER. AFTER THE WIRING PATTERN IS ETCHED, THE CONTACTS FOR THE WIRING LAYER ARE PRINTED AS LINE/SPACE PATTERNS WHICH INTERSECT THE WIRING PATTERN. THE CONTACT PATTERN IS ETCHED INTO THE LOWER, THICKER LAYER WITH AN ETCH PROCESS THAT IS SELECTIVE TO THE UPPER THINNER LAYER. THE CONTACT IS ONLY FOFFI1ED AT THE INTERSECTION POINT OF THE WIRING IMAGE WITH THE CONTACT IMAGE, THEREFORE THE CONTACT IS SELF-ALIGNED TO THE METAL (24).

    Abstract: PROBLEM TO BE SOLVED: To integrate a step move element adjacent to a deep trench capacitor by arranging an FET on one portion of the deep trench capacitor in a substrate, and providing an insulation region with a larger depth than the FET while surrounding the FET. SOLUTION: An FET is arranged on one portion of a deep trench capacitor 13 in a substrate, a travel element gate 17 is arranged on one portion of the deep trench capacitor 13 in the FET, and an n+ diffusion region 23 being separated from the travel element gate 17 by the insulation layer is formed adjacent to the side part of the travel element gate 17. Also, an isolation region 15 being insulated from the travel element gate 17 of the FET is arranged on one portion of the deep trench capacitor that is not covered with the FET, surrounds the FET and is located in the substrate, thus forming a larger depth than the FET and hence integrating the step travel element adjacent to the deep trench capacitor 13.

    Abstract: PROBLEM TO BE SOLVED: To provide a memory cell structure without gate leak current, and an activation method thereof. SOLUTION: The structure includes (a) a substrate, (b) first and second electrode regions 610, 1120 on the substrate, and (c) a third electrode region 1110 arranged between the first electrode region and the second electrode region. When a first write voltage potential is applied between the first electrode and the third electrode region, in response thereto, the third electrode region changes the shape of its own and then, when a predetermined read voltage potential is applied between the first electrode region and the third electrode region, in response thereto, a sense current flows between the first electrode region and the third electrode region. Further, when a second write voltage potential is applied between the second electrode region and the third electrode region, in response thereto, no sense current flows between the first electrode region and the third electrode region.
