Abstract
Semiconductor devices and methods of forming a semiconductor device are disclosed. The device includes a wafer with top and bottom surfaces. The wafer includes edge and non-edge regions. The wafer includes a plurality of devices and partially processed TSV contacts disposed in the non-edge region and a groove disposed at the edge region. The groove enables edges of the wafer to be automatically trimmed off as the wafer is subject to a back-grinding planarization process to expose the TSV contacts in the non-edge region of the wafer.
