Inspection plays a key role in the production of semiconductors, checking for defects and assisting in wafer alignment for a variety of production and test tasks. For example, Suss Microtec's MicroAlign technology for its. ProbeShield automated analytical-probing test environment targets test pads measuring less than 40x40 microns—pads that are too small to permit the use of a cantilevered probe card, because needle scrub lengths can exceed pad dimensions.
