Desk Top Mask Aligner

Mask aligners are used in most microfabrication research laboratories and in even in low- volume production facilities. Almost any microscale device or structure requires more than one photomask step. The job of the contact aligner is to allow its user to align features on a substrate (wafer) to features on a photomask. The production of sophisticated electronic devices may involve ten or more of these alignment steps.
