Claim Text:
1. A method of dispersing semiconductor chips from a wafer of LED semiconductor chips each chip with a d1×d2 area, including m columns and n rows of semiconductor chips, onto a substrate while preserving the neighboring relationship of each chip to each adjacent chip, the method comprising the steps of: dispersing the wafer into sequential columns of semiconductor chips, including m sub-steps, with a first pitch L2 between columns while preserving the neighboring relationship; sequentially dispersing the columns of semiconductor chips into rows of individual chips, including n sub-steps, with a second pitch L1 between rows onto a substrate while preserving the neighboring relationship; the steps of dispersing the wafer into sequential columns and sequentially dispersing the columns of semiconductor chips into rows providing a dilution factor in a range of 9 to 9000.
