Abstract

An electronic device includes an array. In one embodiment, a process for forming an electronic device includes the array, which includes electronic components, can include printing one or more layers as a series of segments onto a workpiece. In one embodiment, a process includes printing a layer onto the workpiece and at least one exposed portion of the chuck. In still another embodiment, a printing head is greater than 0.5 mm from the workpiece. In a further embodiment, “hybrid” printing can be used to help form a thicker layer having a relatively thinner width. In a further embodiment, processes can be used to reduce the likelihood of a stitching defect, nonuniformity of a layer across an array, or a combination thereof. A printing apparatus can be modified to achieve more flexibility in liquid compositions, temperatures or other conditions used in printing a layer.
