  • Semiconductor device having alternating electrically insulative coated leads
    Patent number: 6320258
    Abstract: A package for semiconductor devices is encapsulated in an insulating resin. Multiple conductive leads project from one side of the package. Alternating leads are provided with an insulating coating which projects along a portion of their length. Leads which are not insulated are bent so as to displace them from the plane of the coated leads and space them further away from the coated leads. The bent leads are displaced a sufficient distance to provide a separation in air consistent with spacing standards for high voltage devices.
    Type: Grant

  • Integrated structure pad assembly for lead bonding
    Patent number: 5888889
    Abstract: A process for manufacturing an integrated structure pad assembly for wire bonding to a power semiconductor device chip including a chip portion having a top surface covered by a metallization layer which has a first sub-portion wherein functionally active elements of the power device are present. The chip portion has at least one second sub-portion wherein no functionally active elements of the power device are present. The top surface of the at least one second sub-portion is elevated with respect to the first sub-portion to form at least one protrusion which forms a support surface for a wire.
