Patent ID: 8455872

Claim:
A method of manufacturing a thin film electronic device, the method comprising: applying a first plastic coating (PI- 1 ) directly to a rigid carrier substrate ( 40 ) herein said application comprises: applying a first plastic layer (PI- 1 ); forming a metal pattern over the first plastic layer having pattern portions aligned with the positions in which the thin film electronic elements are subsequently formed; etching the first plastic layer (PI- 1 ) using the formed metal pattern as a mask thereby forming first plastic layer portions for alignment with thin film electronic elements; applying a second plastic layer (PI- 2 ) over the metal pattern; forming said thin film electronic elements over the first plastic coating; applying a second plastic coating over the thin film electronic elements; forming electrodes over the second plastic coating, each electrode forming a circuit together with at least one associated electronic element, and the electrode including a portion lying directly over the associated electronic element, spaced by the second plastic coating; and releasing the rigid carrier substrate from the first plastic coating, by a laser release process.
