Claim 10:
11. 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:
the additive sources are first additive sources;
the printing zone is a first printing zone;
the actuation frequency is a first actuation frequency;
the layer is a first layer;
the additive material is a first additive material;
the patterned layer is a first patterned layer; and
further comprising:
rotating the wafer with respect to the first additive sources and second additive sources distributed across a second printing zone, the second printing zone having a first end located at the center of the wafer, and having a second end, the second end of the second printing zone being located opposite from the first end of the second printing zone; and
operating each second additive source at a second actuation frequency having a maximum that is proportional to a distance of the second additive source from the center of rotation to form a second additive material in a second layer of the electronic device on the wafer concurrently with forming the first layer, the second layer of the second additive material being located within a second patterned layer, the second end of the second printing zone extending to a perimeter of the second patterned layer.
