Abstract

Described is a semiconductor substrate stack, including: a plurality of semiconductor substrates arranged in a stack in which the semiconductor substrates include opposing facing surfaces, wherein the facing surfaces of adjacent semiconductor substrates are separated by a gap, each semiconductor substrate having an edge surface at an exposed edge of the stack. A spacer is attached to one of the facing surfaces of each of the at least one of the semiconductor substrates and extends between adjacent semiconductor substrates to define the gap and mask a central portion of each respective semiconductor substrate.
