Abstract
A semiconductor device comprising a flexible or rigid substrate (10) having a gate electrode (11) formed thereon with a source electrode (14) and a drain electrode (15) overlying the gate electrode (11) and organic semiconductor material (16) disposed at least partially thereover. The source electrode (14) and the drain electrode (15) each have a non-linear boundary segment that effectively extends the channel width between these two electrodes to thereby increase the current handling capability of the resultant device. In many of the embodiments, any of the above elements can be formed through contact or non-contact printing. Sizing of the resultant device can be readily scaled to suit various needs.
