METHOD OF DEBONDING WORK-CARRIER PAIR WITH THIN DEVICES

Disclosed is a thin subject assisted debonding method for separating temporarily bonded workpiece-carrier pair. The thin subject can be a thin wire, or thin filament, or thin blade. The thin subject can be applied between the workpiece and carrier pair in association with laser debonding or mechanical debonding to provide well controlled and targeted wedging function to the delaminating temporary adhesive and its adjacent substrate to which it is separating from. The workpiece can be a semiconductor wafer that has been thinned and processed, and the carrier can be a semiconductor non-device wafer or any other rigid substrate such as a glass wafer or panel. The application of a thin subject between the workpiece and carrier during debonding provides the advantage of high throughput and low defect rate.

Method and Apparatus for Display Screen Shield Replacement
20190270212 · 2019-09-05 · ·

A method and apparatus for replacement of damages display shield (typically glass) covering a display screen on a device, typically a mobile phone. Mobile phones have an electronic display protected by a glass shield. Between the glass and the display is often a plastic polarizing or other intermediary sheet. Removal of a damage glass can be accomplished by cutting thru the polarizer with a moving wire or blade. This separates the glass from the sensitive display and allows replacement of the glass without damaging the more expensive display.
