Abstract

We show HIFETs fabricated completely by printing methods in ambient air on a low-cost plastic substrate (Mylarr A). In this work the ink-jet printing (IJP) method was used for printing all electrodes, while the semiconductor and insulator layers (for which patterning is not necessary) were applied with the roll-to-roll reverse gravure coating (RGC) technique. IJP is a low-cost flexible non-contact direct roll-to-roll compatible printing technique that produces patterns at high resolution (1-100 =m) with low material consumption. The RGC technique, on the other hand, is not used for patterning, but has the advantage of producing thin homogeneous layers for a wide range of ink viscosities.
