Selectable capacitors are used to modify performance characteristics of functional circuit elements of an integrated circuit (IC). In an embodiment, the decoupling capacitors are implemented as additional or alternative mounting pads on a surface of the IC. At least one selectable capacitor is provided for each IC circuit element, such as a logic network, whose operational characteristic(s) is predicted to be and is actually identified as sub-optimal through IC testing, particularly following a process change, a mask shrink, operation of the IC at higher clock frequency, or the like. Expensive redesign is avoided by selectively coupling capacitors into the IC circuit element as needed, under control of selector logic that is responsive to control signals. Methods of operation, as well as application of the apparatus to an electronic assembly and an electronic system, are also described.

An electronic assembly is provided. An electronic substrate of the assembly has a plurality of conductive lines to transmit signals, and a cooling opening therethrough. The cooling opening has an inlet to allow fluid into the electronic substrate, a section in the electronic substrate through which the fluid flows from the inlet, and an outlet from which the fluid flows from the section out of the electronic substrate. A semiconductor die of the assembly is mounted to the electronic substrate. The die has an electronic circuit connected to the metal lines so that signals are transmitted between the electronic circuit and the metal lines, operation of the electronic circuit causing heating of the die, heat being transferred from the die to the electronic substrate from where heat is transferred to the fluid flowing through the section.

An integrated circuit (IC) is provided. The IC includes a silicon substrate and a dielectric layer formed upon the silicon substrate. The IC further includes a terminal metal layer (TML) formed upon the dielectric layer. The dielectric layer and the TML form a die active area.

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.
