Printed electronic device

摘要

This invention generally relates to a patterned substrate for an electronic device and to electronic devices, device arrays, field effect transistors and transistor arrays comprising the patterned substrate. The invention also relates to a logic circuit, display, memory or sensor device comprising the patterned substrate. Further the invention relates to a method of patterning a substrate for an electronic device. In an embodiment, a patterned substrate for an electronic device comprises: a first body having an edge; a second body comprising an elongate plurality of printed droplets having an edge adjacent to and substantially aligned to said first body edge; and a separation between said first body edge and said second body edge, wherein said elongate plurality of printed droplets is at an angle of about 5 degrees to about 90 degrees to said first body edge.

主权项

1. A patterned substrate for an electronic device, comprising:
a source electrode in a form of a first elongate body having a pair of long edges and a pair of short edges, wherein at least one edge of the pair of long edges is a straight long edge; a drain electrode in a form of a second elongate body comprising a plurality of printed droplets, the second elongate body having a pair of long edges and a pair of short edges and an axis along a straight line between centers of two adjoining droplets, wherein a first short edge of the pair of short edges of the second elongate body is in close proximity to and parallel to said straight long edge of said first elongate body; and a submicrometer separation formed by repulsion between said straight long edge of said first elongate body and said first short edge of said second elongate body, wherein said axis of said plurality of printed droplets is at an angle of 90 degrees to said straight long edge of said first elongate body and said first elongate body and said second elongate body together form a T shape.
