Patent number: 6093936Abstract: A silicon semiconductor integrated circuit includes an insulative field oxidation layer which substantially does not encroach under active circuit elements of the integrated circuit. The field oxidation layer is formed of oxidized amorphous silicon created by bombardment of a silicon substrate with noble gas ions. The amorphous silicon oxidizes at a rate much faster than crystalline silicon so that when the field oxidation layer is formed crystalline silicon foundations for the active circuit elements are left substantially intact. The crystalline silicon foundations are formed by using appropriate shield elements during the noble gas ion bombardment. This noble gas ion bombardment also has the advantage of eliminating dislocation defects which may be present in the field oxidation area so that these defects do not propagate into the crystal lattice of the silicon during subsequent heating and cooling cycles.Type: GrantFiled: August 19, 1997Date of Patent: July 25, 2000Assignee: LSI Logic CorporationInventors: Abraham Yee, Sheldon Aronowitz, Yu-Lam Ho

Patent number: 5796130Abstract: A novel configuration for MOS devices employed in a partially generic gate array type chip having large numbers of generally MOS devices. The MOS devices have a non-rectangular configuration and include at least a first and second region of conductivity type differing from the conductivity type of the gate array substrate that are separated by a channel over which an electrode strip such as a gate is formed. The non-rectangular configuration of the MOS devices provides a space savings that permits the presence of a greater number of devices on a single chip as compared to conventional gate array chips. In accordance with another aspect of the invention one or more patternable busses of conductive material, such as polysilicon, interconnect electrode strips of the MOS devices, such as gates strips, that are made of the same conductive material as the busses.Type: GrantFiled: December 26, 1995Date of Patent: August 18, 1998Assignee: LSI Logic CorporationInventors: Tim Carmichael, Gobi Padmanabhan, Abraham Yee, Stanley Yeh

Patent number: 5723896Abstract: An integrated circuit structure vertically isolated electrically from the underlying substrate is formed in/on a single crystal semiconductor substrate, such as a silicon semiconductor wafer, by first implanting the substrate with a sufficient dosage of noble gas atoms to inhibit subsequent recrystallization of the semiconductor lattice in the implanted region during subsequent annealing, resulting in the formation of an isolation layer comprising implanted noble gas atoms enmeshed with semiconductor atoms in the substrate which has sufficient resistivity to act as an isolation layer. The preferred noble gases used to form such isolation layers are neon, argon, krypton, and xenon. When neon atoms are implanted, the minimum dosage should be at least about 6.times.10.sup.15 neon atoms/cm.sup.2 to inhibit subsequent recrystallization of the silicon substrate. When argon atoms are implanted, the minimum dosage should be at least about 2.times.10.sup.15 argon atoms/cm.sup.2.Type: GrantFiled: December 16, 1996Date of Patent: March 3, 1998Assignee: LSI Logic CorporationInventors: Abraham Yee, Sheldon Aronowitz

Patent number: 5721151Abstract: A plurality of macro-arrays are formed on a semiconductor substrate. Each macro-array includes a logic area in which a plurality of interconnectable logic gates are formed, and an Input/Output (I/O) area in which a plurality of I/O devices are formed. I/O terminals are formed outside the I/O area, which enable the logic devices of the macro-arrays to be interconnected with the logic devices of the other macro-arrays via the I/O devices. Alternatively, connections can be made directly to the logic devices. The interconnections are made using a pattern of conductors such that the macro-arrays are linked to form a composite gate array which provides a programmed logical functionality. A number of contiguous macro-arrays which provide the required number of gates are used, with the unused macro-arrays being cut away and discarded.Type: GrantFiled: June 7, 1995Date of Patent: February 24, 1998Assignee: LSI Logic CorporationInventors: Gobi Padmanabhan, Abraham Yee

Patent number: 5644143Abstract: Various techniques for forming superconductive lines are described whereby superconductive lines can be formed by stamping, etching, polishing, or by rendering selected areas of a superconductive film (layer) non-superconductive. The superconductive material can be "perfected" (or optimized) after it is formed into lines (traces). In one embodiment, trenches are etched in a substrate, the trenches are filled with superconductive material, and any excess superconductive material overfilling the trenches is removed, such as by polishing. In another embodiment, superconductive lines are formed by rendering selected areas of a superconductive layer (i.e., areas other than the desired superconductive lines) non-superconductive by "damaging" the superconductive material by laser beam heating, or by ion implantation. Superconductive lines formed according to the invention can be used to protect semiconductor devices (e.g.Type: GrantFiled: May 30, 1995Date of Patent: July 1, 1997Assignee: LSI Logic CorporationInventors: Michael D.

Patent number: 5561319Abstract: A CMOS integrated circuit structure is disclosed having a patterned nitride passivation layer, wherein the nitride is patterned such that it does not overlie the thin gate oxide portions of one or more of the MOS devices.

Patent number: 5538907Abstract: A CMOS integrate circuit has improved protection to damage from electrostatic discharge (ESD) events because the circuit is formed with a virtual lateral bipolar transistor submerged in the morphology of the integrated circuit beneath an active circuit element of the circuit, and being formed by impurity atoms implanted into the substrate structure as ions which disperse laterally to form a dispersed charge permeation zone through which surge current from an ESD is conducted safely at a current level sufficiently low that the substrate material of the integrated circuit is not damaged. The integrated circuit may be formed with an intrinsic zener diode having a reverse bias breakdown voltage high enough to not interfere with the normal operation of the integrated circuit, and low enough to allow surge current from an ESD event to safely flow to ground potential.Type: GrantFiled: May 11, 1994Date of Patent: July 23, 1996Assignee: LSI Logic CorporationInventors: Sheldon Aronowitz, Rosario Consiglio, Abraham Yee

Patent number: 5516731Abstract: A technique for improving the radiation hardness and hot-electron resistance of a CMOS integrated circuit is described whereby undesirable hydrogen ions may be vented through any holes, such as contact holes, in an overlying passivation layer by applying an elevated temperature and/or electrical bias to the integrated circuit die. The elevated temperature and electrical bias serve to accelerate the process by which hydrogen vents from the die. The elimination of unwanted hydrogen significantly reduces threshold shifts in the CMOS integrated circuit, providing greater radiation hardness and hot-electron resistance.Type: GrantFiled: June 2, 1994Date of Patent: May 14, 1996Assignee: LSI Logic CorporationInventors: Shahin Toutounchi, Abraham Yee, Alexander H.
