  • Method of manufacturing a high-yield solder bumped semiconductor wafer
    Patent number: 4898320
    Abstract: Disclosed is a method of manufacturing a high-yield solder bumped semiconductor wafer. The method comprises providing a non-solderable transfer substrate having a transfer surface for receipt of solder material; depositing solder material onto the transfer surface to form solder bumps in a predetermined pattern; aligning solderable conductive elements of a semiconductor wafer with the predetermined solder bumps on the transfer surface; and reflowing the patterned solder bumps into wetted contact with the wafer conductive elements.
    Type: Grant

    Date of Patent: February 6, 1990
    Assignee: Honeywell, Inc.
    Inventors: Thomas J. Dunaway, Richard K. Spielberger, Lori A. Dicks
  • Controlled compression furnace bonding
    Patent number: 4892245
    Abstract: Disclosed is a system and method for controlled compression furnace bonding of a semiconductor chip to conductive elements of a leadframe. The system comprises a holding member having a chip support surface for supporting a semiconductor chip and a positioning system for precisely positioning conductive elements of a leadframe with corresponding bonding locations on the semiconductor chip. A furnace heating system comprising a furnace is employed for heating and bonding the conductive elements to the chip bonding locations.
