  • Fluoropolymer-carbon dioxide compositions and methods of processing fluoropolymers
    Patent number: 7115685
    Abstract: Fluoropolymer materials containing tetrafluoroethylene monomers, such as PTFE, are significantly swollen by supercritical carbon dioxide at high temperatures and pressures. The swollen fluoropolymer is processable by molding, extrusion, and other techniques. In addition, the fluoropolymer may be sintered at significantly lower temperatures compared to a nonswollen fluoropolymer material. The melting temperature of fluorinated polymers containing tetrafluoroethylene and triflouroethylene monomers which are swollen with supercritical carbon dioxide is significantly reduced, thereby permitting manufacturing operations such as extruding and molding to be performed at lower temperatures and with reduced risk of decomposition.

  • Method of fabricating SiGe Bi-CMOS device
    Patent number: 7115459
    Abstract: Provided is a method of fabricating a silicon germanium (SiGe) Bi-CMOS device. In the fabrication method, the source and drain of the CMOS device is formed using a silicon germanium (SiGe) heterojunction, instead of silicon, thereby preventing a leakage current resulting from a parasitic bipolar operation. Further, since the source and drain is connected with an external interconnection through the nickel (Ni) silicide layer, the contact resistance is reduced, thereby preventing loss of a necessary voltage for a device operation and accordingly, making it possible to enable a low voltage and low power operation and securing a broad operation region even in a low voltage operation of an analogue circuit.
