Abstract
Abstract The invention is related to electronic and more specifically to photo-electronic devices manufactured by means of thin film layering techniques. The invention proposes the use of polymer, copolymer, polyamide and similar organic casting materials, in layers 500 to 10,000 angstroms thick, as protective barriers between layers where the processing of one layer would be adversely affected by or would damage an adjacent previously formed layer.
