Abstract
An array of crystalline silicon dies on a substrate and a method for yielding the array are provided. The method comprises: delineating an array of die areas on a crystalline semiconductor wafer; implanting the die areas with hydrogen ions; overlying the die areas with a layer of polymer to form, for each die, an aggregate including a die area first wafer layer; polymerically bonding an optically clear carrier to the die areas; thermally annealing the wafer to induce breakage in the wafer; forming, for each die, an aggregate wafer second layer with a thickness less than the die thickness; and, for each die, conformably attaching the aggregate wafer second layer to a substrate. The substrate can have an area of up to approximately two square meters and the wafer second layer can have a thickness of greater than and equal to approximately 20 nanometers.
