  • Patent number: 7475368
    Abstract: A system, a method and a computer program product for analyzing a circuit design provide for discretizing the circuit design into a series of pixels. A fraction of at least one constituent material is determined for each pixel. A deflection is also determined for each pixel. The deflection is predicated upon a planarizing of the pixel, and it is calculated while utilizing an algorithm that includes the fraction of the at least one constituent material. A series of deflections for the series of pixels may be mapped and evaluated.

  • Patent number: 6892781
    Abstract: A fixture having a bottom plate, top plate and an expansion block interposed between the bottom plate and top plate. A workpiece is positioned between the expansion block and bottom plate. When the fixture is heated, there is a net displacement exerted by the expansion block so as to apply pressure to the workpiece. The pressure applied by the fixture to the workpiece is due solely to the thermal expansion of the fixture when it is heated.

  • Patent number: 6518392
    Abstract: A novel dielectric composition is provided that is useful in the manufacture of integrated circuit devices and integrated circuit packaging devices. The dielectric composition is prepared by imidizing and curing an oligomeric precursor compound comprised of a central polybenzoxazole, polybenzothiazole, polyamic acid or polyamic acid ester segment end-capped at each terminus with an aryl-substituted acetylene moiety such as an ortho-bis(arylethynyl)aryl group, e.g., 3,4-bis(phenylethynyl)phenyl. Integrated circuit devices, integrated circuit packaging devices, and methods of synthesis and manufacture are provided as well.

  • Patent number: 6262390
    Abstract: A method to repair Aluminum Nitride (AlN) substrates is disclosed wherein a frequency doubled Q-switched Nd:YAG laser is used to remove unwanted metallurgy. The substrate is place in a liquid filled work chamber which acts to prevent metallic species of AlN from forming. The repair site can be sealed with a novel polymer coating to prevent contamination or corrosion. Repairs can be made to buried or surface metallurgy.

  • Patent number: 6046074
    Abstract: A module for encapsulating a microelectronic device has a polished mating surface around the periphery of the substrate on which is deposited at least one thin film sealband fabricated at a temperature no greater than about 400.degree. C. The sealband has a thickness of less than about 0.001 in. and comprising a metal capable of wetting molten solder which has a melting point no greater than about 400.degree. C. and adhering to the solder after solidification. A layer of the solder is disposed between the sealbands of the cap and substrate forming a hermetic seal for the module.
