Abstract
A precisely spaced stack of substrate layers comprises a plurality of substrate layers disposed one above another in a stacked configuration and having a glass layer coating on one of each pair of adjacent substrates, the glass layer having a thickness such that the sum of the thicknesses of the glass layer and the substrate to which the glass layer is fused is approximately equal for substantially all of the substrate layers. A polymer adhesive is disposed intermediate the glass layer and a substrate layer such that adjacent substrate layers are bonded together. By controlling the height of each pair of substrate and glass layers, a precisely spaced and strongly bonded stack of substrate layers is formed.
