Circuit-on-wire

摘要

A circuit-on-wire (CoW) is provided that is made from a flexible metal wire with an outer surface, and a plurality of discrete electrical control devices formed in series along the metal wire outer surface. Each control device may have an electrical contact accessible through the metal wire. In one aspect, the control device may have a via through the metal wire from the top surface to the bottom surface with a second electrical contact accessible through the via. In addition, the control devices may have a top surface with an accessible third electrical contact. For example, the control device may be a first thin-film transistor (TFT), with a gate electrode accessible through the metal wire, wherein the second electrical contact is a first source/drain (S/D) electrode, and wherein the third electrical contact is a second S/D electrode. Using the above-described CoW, a woven active matrix array can be fabricated.

1. A woven active matrix array comprising:
a set of parallel first metal lines aligned in a first direction; a set of parallel second metal lines aligned in a second direction orthogonal to the first direction, each second metal line having a top surface and a bottom surface; wherein the first metal lines intersect the second metal lines to form pixel regions; wherein a plurality of metal lines from the second metal lines comprise serially configured circuit-on-wire (CoW) control devices overlying an outer surface of the second metal line; wherein each control device is associated with a corresponding pixel region; and, wherein a plurality of control devices each comprises:
a via through the second metal wire from the top surface to the bottom surface; and,a second electrical contact accessible through the via.
