Abstract
Disclosed herein is a cost effective, efficient, massively parallel multi-wafer test cell. Additionally, this test cell can be used for both single-touchdown and multiple-touchdown applications. The invention uses a novel “split-cartridge” design, combined with a method for aligning wafers when they are separated from the probe card assembly, to create a cost effective, efficient multi-wafer test cell. A “probe-card stops” design may be used within the cartridge to simplify the overall cartridge design and operation.
