Abstract
An active component array includes a target substrate having one or more contacts formed on a side of the target substrate, and one or more printable active components distributed over the target substrate. Each active component includes an active layer having a top side and an opposing bottom side and one or more active element(s) formed on or in the top side of the active layer. The active element(s) are electrically connected to the contact(s), and the bottom side is adhered to the target substrate. Related fabrication methods are also discussed.
Claims32
An active component array, comprising:
- at least one printable electronic component comprising an active layer including at least one active element on a first surface thereof and a conductive element on a second surface thereof opposite the first surface, the conductive element on the second surface being configured to provide an electrical coupling to the at least one active element on the first surface, wherein the at least one printable electronic component includes a broken portion of a tether adjacent a periphery thereof;
- and
- a target substrate different from the active layer and including one or more electrical contacts on a surface thereof, wherein the at least one printable electronic component is printed on the target substrate such that the conductive element on the second surface thereof is in contact with a respective one of the electrical contacts on the surface of the substrate.
A method of fabricating an active component array, the method comprising:
- providing at least one printable electronic component comprising an active layer including at least one active element on a first surface thereof and a conductive element on a second surface thereof opposite the first surface, the conductive element on the second surface being configured to provide an electrical coupling to the at least one active element on the first surface, wherein the at least one printable electronic component includes a broken portion of a tether adjacent a periphery thereof;
- and
- printing the at least one printable electronic component on a target substrate different from the active layer and including one or more electrical contacts on a surface thereof such that the conductive element on the second surface of the at least one printable electronic component is in contact with a respective one of the electrical contacts.
