    摘要: An SOI chip having an isolation barrier. The SOI chip includes a substrate, an oxide layer deposited on the substrate, and a silicon layer deposited on the oxide layer. A gate is deposited above the silicon layer. A first metal contact is deposited above the gate to form an electrical contact with the gate. Second and third metal contacts are deposited to form electrical contacts with the silicon layer. The isolation barrier extends through the silicon layer and the oxide layer, and partially into the substrate, to block impurities in the oxide layer outside the isolation barrier from diffusing into the oxide layer inside the isolation barrier. The isolation barrier surrounds the gate, the first metal contact, the second metal contact, and the third metal contact--which define an active chip area inside the isolation barrier. A method of manufacturing the SOI chip is also disclosed.

    摘要: An electrically programmable fuse buried under quartz and layers of polyimide with a specific structure to enhance its "thermal" capabilities. The fuse is designed to "blow" and cool off quickly so as not to cause damage to areas above and surrounding the fuse. A passivation layer is added above the fuse to act as a heat sink and absorb and redistribute the heat generated from one localized area to a broader and cooler area. The materials used for the fuse and the heat sink are selected to be compatible with both oxide and polyimide personalization schemes. Modeling of the fuse enables optimizing the characteristics of the fuse, particularly to transmit to the surface of the passivation layer the thermal wave created during programming of the fuse.

    摘要: A noise immune fuse having sub-micron dimensions which can be programmed by an electrically and thermally synchronized event. The fuse includes a pair of fuse links in close proximity of each other, a layer of thermally conductive and electrically insulating material thermally coupling the two links forming the pair, and means for programming the first link by prompting the second link to gate the energy transfer between the links via the coupling layer. By combining thermal and electrical pulses to perform the programming function, the reliability of the fuse structure is greatly enhanced when compared to that of a single element fuse.

    摘要: An improved antifuse uses metal penetration of either a P-N diode junction or a Schottky diode. The P-N junction, or Schottky diode, is contacted by a diffusion barrier such as TiN, W, Ti-W alloy, or layers of Ti and Cr, with a metal such as Al. Al-CU alloy, Cu, Au, or Ag on top of the diffusion barrier. When this junction is stressed with voltage pulse producing a high current density, severe joule heating occurs resulting in metal penetration of the diffusion barrier and the junction. The voltage drop across the junction decreases by about a factor of ten after the current stress and is stable thereafter. Alternatively, a shallow P-N junction in a silicon substrate is contacted by a layer of metal that forms a silicide, such as Ti, Cr, W, Mo, or Ta. Stressing the junction with a voltage pulse to produce a high current density results in the metal penetrating the junction and reacting with the substrate to form a silicide.

    摘要: A fully isolated dielectric structure for isolating regions of monocrystalline silicon from one another and method for making such structure are described. The structure uses a combination of recessed oxide isolation with pairs of parallel, anisotropic etched trenches which are subsequently oxidized and filled to give complete dielectric isolation for regions of monocrystalline silicon. The anisotropic etching preferably etches a buried N+ sublayer under the monocrystalline silicon region and then the trench structure is thermally oxidized to consume the remaining N+ layer under the monocrystalline region and to fully isolate the monocrystalline silicon region between pairs of such trenches.
