1. A method of manufacturing an electronic device comprising:
- a) providing a substrate that comprises at least one plastic material;
b) forming a pattern on at least one surface of said substrate;
c) embedding a non-doping particulate material at and below at least one surface of said substrate, wherein the embedded particles have high concentration at the surface and the concentration decreases with depth inside the substrate;
d) applying a planarization material to the surface of the substrate having the embedded particulate material, forming a planarization layer thereby;
e) forming a thin film electronic device on said surface with said particulate material; and
f) forming a patterned trace layer on the surface of the substrate that lies opposite the surface having the embedded particulate material.

Abstract
A method of manufacturing an electronic device (10) provides a substrate (20) that has a plastic material and has a metallic coating on one surface. A portion of the metallic coating is etched to form a patterned metallic coating. A particulate material (16) is embedded in at least one surface of the substrate. A layer of thin-film semiconductor material is deposited onto the substrate (20).
