Abstract
A method of dispersing semiconductor chips from a wafer of semiconductor chips onto a substrate while preserving the neighboring relationship of each chip to each adjacent chip is disclosed. The method includes dispersing the wafer into sequential columns of semiconductor chips with a first pitch between columns while preserving the neighboring relationship and sequentially dispersing the columns of semiconductor chips into rows of individual chips with a second pitch between rows onto a substrate while preserving the neighboring relationship.
