- Back grinding is a process used in semiconductor packaging to reduce wafer thickness and allow stacking and high-density IC packaging12. The process is divided into three detailed steps34:
- Tape lamination is conducted to attach tape to a wafer.
- The back side of a wafer is ground.
- Wafer mounting is carried out to place the wafer on the tape before the sawing process which separates a chip from a wafer.
