  • Method and apparatus for semiconductor testing at low temperature
    Patent number: 9224659
    Abstract: A method for testing a plurality of semiconductor devices arranged on a strip may include forming an array of semiconductor devices on a frame, wherein contact pads of adjacent semiconductor devices are shorted, partially cutting the strip to electrically isolate individual semiconductor devices in the array, placing the strip on an adhesive tape configured to withstand low temperatures (e.g., below ?20° C. or below ?50° C.), arranging the strip and tape on a test chuck, exposing the test chuck, strip, and tape to temperatures below an ambient temperature and testing the plurality of semiconductor devices while exposed to a low temperature. In one embodiment a KAPTON™ film is used as the adhesive tape.
