Packaging die preparation

The present invention relates to a process for preparing a wafer for chip packaging that minimizes stress and torque on wafer components during back grinding. The wafer has fabricated thereon a plurality of dies in a die side thereof opposite a back side thereof. A protective coating is spun on the die side to protect the dies. The wafer is separated into a plurality of connected pieces by scratching or cutting a recess into streets or scribe lines in the die side. The connected pieces of the wafer are secured to a surface with the back side thereof exposed. Material is removed from the back side of the wafer by chemical, mechanical, or chemical-mechanical methods until each piece is separated or disconnected from the other pieces. The protective coating is removed. The pieces can be situated upon a flexible surface that is stretched to increase the separation between pieces. Each die in the die side of each piece is then packaged into a die package.
