This guide was developed to expedite inter-laboratory experiments used to evaluate or develop standard test methods that involve test-structure measurements or tests. It also facilitates, generally, any electrical tests that require wafer-probe card to make electrical contact to test structures. Widespread use of this guide will afford the efficient and cost-effective use of water-probe test stations because of the need for fewer probe cards and probe-card changes to accommodate the various test structures that may need to be tested.
