Abstract
A method includes applying a compressive force against MEMS structures at a front side of a MEMS wafer using a protective material covering at least a portion of the front side of the MEMS wafer. The method further includes concurrently dicing through the protective material and the MEMS wafer from the front side to produce a plurality of MEMS dies, each of which includes at least one of the MEMS structures. The protective material is secured over the front side of the MEMS wafer to apply pressure to the protective material, and thereby impart the compressive force against the MEMS structures to largely limit movement of the MEMS structures during dicing. A tack-free surface of the protective material enables its removal following dicing.
