WebThe cutting of the support ring is a very critical step in the removal process. Performing the cut with a physical blade creates stress and causes damage to the wafer. This can lead to scallop fractures and subsequent wafer breakage due to micro cracks. WebWe are introducing a grinding method, which grinds the ring section of a wafer, in the TAIKO process. When mounting a TAIKO wafer onto dicing tape, if the height difference between the ring section and TAIKO section is big, a large void is generated between the tape and wafer, which has a negative impact on the dicing.

Cutting and removing of TAIKO rings. Wafer with a thickness of less than 80 micron are stabilized for grinding with a ring on the outer perimeter. Before dicing it is necessary to remove the TAIKO ring. Using this method lowers the risks of thin wafer handling (breakage, edge chipping) and decreases warpage. Webwhich the device wafers are fully cut from the back after carrier wafer bonding. For the edge trimming before bonding, depth of approximately 150-200 µm is cut from the surface of …
