Patent ID: 8648336

Claim:
A method for fabrication of heterojunction polymeric devices, comprising the steps of: a) depositing a layer containing polymer-forming molecules having any one or combination of C—H bonds and Si—H bonds on a surface of a substrate; b) producing, and directing a flux of hyperthermal neutral molecular hydrogen having kinetic energies in a range from about 1 eV to about 100 eV to the layer such that upon impact of hyperthermal neutral molecular hydrogen molecules on molecules containing any one or combination of C—H bonds and Si—H bonds the C—H bonds and Si—H bonds are selectively ruptured resulting in cross-linking of the polymer-forming molecules to form a cured polymer layer on the substrate; and c) repeating steps a) and b) a selected number of times to fabricate a heterojunction polymeric device having said selected number of cured polymer layers formed one on top of the other.
