摘要:
Phenomena such as electromigration and stress-induced migration occurring in metal interconnects of devices such as integrated circuits are inhibited by use of underlying non-planarities. Thus the material underlying the interconnect is formed to have non-planarities typically of at least 0.02 μm in height and advantageously within 100 μm of another such non-planarity. Such non-planarities, it is contemplated, reduce grain boundary movement in the overlying interconnect with a concomitant reduction in void aggregation.

An integrated circuit having an integrated circuit die and at least one height-sensing pad disposed on a top surface of the integrated circuit die and electrically isolated from the die circuitry. At least one bond pad is disposed on a top surface of the integrated circuit die and electrically connected to the die circuitry. The at least one bond pad is configured for wire-bonding to a lead of a leadframe utilizing a height coordinate of the at least one height-sensing pad.

Techniques for detecting damage on an integrated circuit die using a particle suspension solution are disclosed. The particles of the suspension solution preferentially attach to damaged regions on exposed dielectric films or other portions of the die. For example, one aspect of the invention is a method of detecting damage to a dielectric film used in fabricating a die of an integrated circuit. A particle suspension solution is applied to the die and damaged regions of the dielectric film are identified as areas having an accumulation of particles of the particle suspension solution.

Methods and apparatus for performing a wire-bonding operation in an integrated circuit are disclosed. The positions of at least one height-sensing pad and at least one bond pad are determined on a top surface of an integrated circuit die. The height-sensing pad is electrically isolated from the die circuitry and the bond pad is electrically connected to the die circuitry. A bonding tool is lowered to the height-sensing pad, and a height coordinate of the height-sensing pad is then determined. Finally, the bond pad is wire-bonded to a leadframe utilizing the height coordinate of the height-sensing pad.

Embodiments of the invention provide methods and apparatus for managing temperature in integrated circuits. In accordance with an aspect of the invention, an integrated circuit comprises a monitored region defined by three or more edges. What is more, the integrated circuit comprises at least two temperature sensors for each of the three or more edges. The temperature sensors are arranged along the three or more edges such that each edge has substantially the same arrangement of temperature sensors. Thermal management of the integrated circuit may be accomplished by modifying functional aspects of the integrated circuit in response to measurements provided by the temperature sensors.
摘要:
The specification describes an improved mechanical electrode structure for MOS transistor devices with elongated runners. It recognizes that shrinking the geometry increases the likelihood of mechanical failure of comb electrode geometries. The mechanical integrity of a comb electrode is improved by interconnecting the electrode fingers in a cross-connected grid. In one embodiment, the transistor device is interconnected with gate fingers on a lower metaliization level, typically the first level metal, with the drain interconnected at a higher metal level. That allows the drain fingers to be cross-connected with a vertical separation between drain and gate comb electrodes. The cross-connect members may be further stabilized by adding beam extensions to the cross-connect members. The beam extensions may be anchored in an interlevel dielectric layer for additional support.
