A Study of the Effect of Back Grind Wheels on Wafer .
There were a need of thinner Integrated Circuit or IC in order to fit in to thinner applications like mobile phones. One of the major semiconductor process that enables miniaturization was wafer back grinding. The process involves wafer thinning to a required thickness with the use of back grinding wheels that serve as the abrasive material.

Wafer grinding, ultra thin, TAIKO dicinggrinding service
TAIKO is a DISCO developed wafer back grinding method. By enabling an outer support ring to the wafer (the TAIKO ring, Japanese for drum), back grinding is performed on the inner circular area of the wafer, while leaving an edge of a few millimeters unprocessed. Taiko simplifies thin wafer handling and lowers warpage.
