Claim 19:
20. A method of forming an electronic device, comprising:
locating a semiconductor wafer adjacent additive sources distributed across a printing zone, the printing zone having a first end located adjacent a center of the wafer, and having a second end located opposite from the first end;
rotating the semiconductor wafer with respect to the additive sources, wherein the semiconductor wafer has a center of rotation; and
operating each additive source at integer multiples of an incremental period corresponding an actuation frequency having a maximum that is proportional to a distance of the additive source from the center of rotation to form an additive material in a layer of the electronic device over the wafer, the layer of the additive material being located within a patterned layer, the second end of the printing zone extending to a perimeter of the patterned layer,
wherein:
operating each additive source includes providing actuation signals at the actuation frequency to the additive source, the actuation signals including formation actuation signals, wherein the additive source forms a predetermined uniform amount of the additive material on the wafer for each formation actuation signal provided to the additive source; and
the actuation signals include null actuation signals, wherein the additive source omits formation of the additive material on the wafer for each null actuation signal provided to the additive source.
