Abstract:
AN ANTI-FUSE STRUCTURE THAT CAN BE PROGRAMMED AT LOW VOLTAGE AND CURRENT AND WHICH POTENTIALLY CONSUMES VERY LITTLE CHIP SPACES AND CAN BE FORMED INTERSTITIALLY BETWEEN ELEMENTS SPACED BY A MINIMUM LITHOGRAPHIC FEATURE SIZE IS FORMED ON A COMPOSITE SUBSTRATE SUCH AS A SILICON-ONINSULATOR WAFER BY ETCHING A CONTACT THROUGH AN INSULATOR TO A SUPPORT SEMICONDUCTOR LAYER, PREFERABLY IN COMBINATION WITH FORMATION OF A CAPACITOR-LIKE STRUCTURE REACHING TO OR INTO THE SUPPORT LAYER. THE ANTI-FUSE MAY BE PROGRAMMED EITHER BY THE SELECTED LOCATION OF CONDUCTOR FORMATION AND/OR DAMAGING A DIELECTRIC OF THE CAPACITOR-LIKE STRUCTURE. AN INSULATING COLLAR (38, 90) IS USED TO SURROUND A PORTION OF EITHER THE CONDUCTOR (42, 100) OR THE CAPACITOR-LIKE STRUCTURE TO CONFINE DAMAGE TO THE DESIRED LOCATION.HEATING EFFECTS VOLTAGE AND NOISE DUE TO PROGRAMMING CURRENTS ARE EFFECTIVELY ISOLATED TO THE BULK SILICON LAYER, PERMITTING PROGRAMMING DURING NORMAL OPERATION OF THE DEVICE. THUS THE POTENTIAL FOR SELF-REPAIR WITHOUT INTERRUPTION OF OPERATION IS REALIZED.(FIG 6)
Abstract:
A programmable device includes a substrate (10); an insulator (13) on the substrate; an elongated semiconductor material (12) on the insulator, the elongated semiconductor material having first and second ends, and an upper surface S; the first end (12a) is substantially wider than the second end (12b), and a metallic material is disposed on the upper surface; the metallic material being physically migratable along the upper surface responsive to an electrical current I flowable through the semiconductor material and the metallic material.

PROBLEM TO BE SOLVED: To provide a dual work function semiconductor structure with borderless contact and a method for manufacturing the same. SOLUTION: The structure may comprise a substantially cap-free gate 108 and conductive contacts 134 and 170 to a diffusion part 116 adjacent to the cap-free gate, and the conductive contact may include a field effect transistor (FET) borderless to the gate. Because the structure is a dual work function structure, the conductive contact is allowed to extend over the cap-free gate without being electrically connected thereto. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide the structure and the method of forming an integrated circuit including a low programming voltage anti-fuse on a semiconductor substrate. SOLUTION: This integrated circuit is formed by doping a part of a semiconductor substrate with nitrogen and a charge carrier dopant source, forming a thin dielectric that is destroyed by the application of breakdown voltage on the doped portion of the semiconductor substrate, forming a first conductor that is separated from the semiconductor substrate by the thin dielectric, and forming a second conductor that is conductively connected with the doped portion of the semiconductor substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for a fuse programming integrated circuit in which fuses are used in common by redundant elements. SOLUTION: A method and a device for initializing an integrated circuit by the use of the compressed data from a remote fuse box are capable of reducing fuses in number required for repairing or customizing the integrated circuit, and grouping the fuses outside macros which are repaired by the fuses. The remote position of the fuses improves the arrangement of the macros, having redundant repairing performances in flexibility and enables the fuses to be properly grouped for facilitating the usability of programming and the layout of circuits. The fuses are formed into columns and rows, to represent control words and run-length compressed data and to provide more repairing points per fuse. The data are loaded into a shift register in series and shifted to macro positions, for controlling the selection of redundant circuits, so that defective integrated circuits can be repaired, and the logic is customized.

PROBLEM TO BE SOLVED: To provide a semiconductor structure wherein the thermal conductivity is enhanced, and its manufacturing method. SOLUTION: During manufacturing of selected electronic components, silicon is formed at selected position on a substrate. Dielectric isolation regions are formed in an upper silicon layer and filled with a thermal conductive material.
