Abstract
In accordance with a specific embodiment, a method of processing a semiconductor substrate is disclosed whereby the substrate is thinned, and the dice formed on the substrate are singulated by a common process. Trench regions are formed on a backside of the substrate. An isotropic etch of the backside results in a thinning of the substrate while maintaining the depth of the trenches, thereby facilitating singulation of the die.
