Transistor structures on printer paper.
(a) Schematic process of the screen-printing approach. Top middle inset shows an optical image of the enlarged source/drain pattern, where the light blue part is covered by emulsion. Top right inset is an SEM image of channel area defined between two fingers. (b) Surface roughness (root mean square) after different fabrication processes. (c) SEM surface image of the paper substrate. (d) Schematic cross sectional structure of the transistor. (e) SEM cross sectional image of the transistor under the drain electrode area. (f) SEM surface image of the screen-printed gate electrode on paper.
