Abstract
The roughness and structural height of printed metal lines is used to pin a fluid. This fluid deposits a top contact material which is connected to the bottom printed contacts through pinholes in the hydrophobic polymer layer. This results in a sandwich-like contact structure achieved in a self-aligned deposition process and having improved source-drain contact for all-additive printed circuits. In one form, the present technique is used for thin film transistor applications, but it may be applied to electrodes in general.
