Abstract
Systems and methods are provided for testing partially completed three-dimensional ICs. Example methods may incorporate one or more of the following features: design for testing (DFT); design for partial wafer test; design for partial probing; partial IC probecards; partial IC test equipment; partial IC quality determinations; partial IC test optimization; and partial test optimization. Other aspects may also be included. Systems and methods incorporating these features to test partially completed three-dimensional ICs may result in saved time and effort, and less scraped material, as the partial device is not built any further when a bad partial device is detected. This results in lower costs and higher yield.
