Abstract:
1. A method of utilizing a sacrificial template with three dimensional features for manufacturing a device comprising the steps; providing a sacrificial template with three dimensional features comprising first and second surfaces; depositing a first layer over the first surface; forming a pattern in the first layer and a feature into the first surface; depositing a first portion of an active layer operable in the device over the patterned first layer and feature; recrystallizing the first portion of the active layer such that at least 90% of the recrystallized active layer has crystal grains of at least 1 micron in size in a lateral dimension; and removing the sacrificial template with the three dimensional features by one or more steps of chemical reaction, sputter etching, thermal ablation, etching a release layer, and flexing a mechanical release layer acting on the second surface.
