STRUCTURES FOR INTERDIGITATED FINGER CO-EXTRUSION

A device has isolated structures on a substrate, the isolated structures formed of a first material, the structures extending vertically from the substrate, and a second material on the substrate surrounding the isolated structures. A method of forming isolated structures includes depositing a first...

Beschreibung
Zusammenfassung:	A device has isolated structures on a substrate, the isolated structures formed of a first material, the structures extending vertically from the substrate, and a second material on the substrate surrounding the isolated structures. A method of forming isolated structures includes depositing a first material and a second material on a substrate using a co-extrusion print head by applying pressure to the first material and the second material, periodically reducing the pressure applied to the first material to stop deposition of the first material while continuing to apply pressure to the second material to form isolated structures of the first material extending vertically from the substrate surrounded by the second material on the substrate, and removing the second material to leave isolated structures on the substrate.
