  • Patent number: 9499921
    Abstract: The process for manufacturing a silicon wafer includes steps for mounting a float zone silicon work piece for exfoliation, energizing a microwave device for generating an energized beam sufficient for penetrating an outer surface layer of the float zone silicon work piece, exfoliating the outer surface layer of the float zone silicon work piece with the energized beam, and removing the exfoliated outer surface layer from the float zone silicon work piece as the silicon wafer having a thickness less than 100 micrometers.

  • Patent number: 9404198
    Abstract: The process for manufacturing wafers includes the steps of mounting an ingot as a work piece in a manner that permits rotation about a longitudinal axis of rotation and rotating the ingot about its longitudinal axis of rotation to permit a microwave device that generates an energized beam to penetrate an outer surface layer thereof. Furthermore, the process includes exfoliating the outer surface layer with the energized beam, removing the exfoliated outer surface layer from the ingot as a continuous planar strip and cutting the continuous planar strip into a wafer.
