    摘要: A beam column array included alignment marks within to enable alignment of beams with respect to each other. Specifically, the array includes an array of beam columns, each column having at least once lens. A plurality of alignment marks are located beneath the lens. A method of using the array includes: scanning a plurality of beams in a beam column array over a plurality of alignment marks; and determining beam centroid positions of the beams with respect to each other based on data from the scanning.
