Assembling an electrode device

1. A method of assembling an electronic device comprising:

a) providing a transparent conductive polymer layer coated over a first support;

b) pattern-wise forming a transparent mask with at least one opening over the conductive polymer;

c) subjecting the masked conductive polymer to treatment through the opening that changes conductivity of the conductive polymer by at least one order of magnitude in areas not covered by the mask to form a first electronic component; and

d) securing the first electronic component having the mask to a second electronic component, thereby forming the electronic device.

2. The method of claim 1 wherein the mask contains polyvinyl acetal.

3. The method of claim 2 wherein step (b) includes thermally transferring the mask from a donor element.

4. The method of claim 1 wherein the second electronic component is formed using elements (a) through (c) to provide a different conductive pattern than the first electronic component.

5. The method of claim 1 wherein element (d) includes using a transparent adhesive, and wherein the transparent adhesive and mask have indeces of refraction that are within 0.05 of each other.

6. The method of claim 1 wherein element (d) includes using the mask as an alignment reference.

7. The method of claim 6 including forming a fiduciary mark on the mask.

8. The method of claim 7 including using a common patterning step to apply the mask and fiduciary mark.
