| 1. A method, comprising:
forming a first active electronic layer having selected areas on a substrate;
printing an array of pillars in the selected areas on the first active electronic layer;
dispensing a curable polymer over the array of pillars;
molding the curable polymer by contacting the curable polymer with a mold structure to displace the curable polymer from upper
surfaces of the pillars;
curing the curable polymer to produce a hardened polymer; and
removing the array of pillars to leave an array of holes in the hardened polymer.
