Abstract:
A method of forming a die from a wafer comprising:forming a trench in a first surface of said wafer around said die wherein a portion of at least one sidewall of said trench is a peripheral edge of said die, a depth of said sidewall is at least as large as a thickness of said edge, and minimal damage is done to said die by forming said trench; producing a through-cut from a bottom surface of said trench to a second surface of said wafer opposite said first surface to form a section containing said die, wherein said through-cut is displaced from said edge by a length, thereby creating a shelf of said length on said section between said edge and said through-cut; mounting said one or more sections onto a holding member; and thinning said one or more section from said second surface until a distance between said first and second surfaces is said thickness.
