New manual wafer wand for 4 x 4-inch and 6 x 6-inch square substrates.The lockable tweezers are used in handling alumna substrate and lithography mask handling applications.

The patent-pending design handles a fragile substrate softly but firmly without excessive compression force. A latching mechanism that locks the tweezers in the holding position adds security in handling the delicate substrate. The surfaces of the substrate are much less likely to be scratched in contrast to conventional metal tweezers. Also, the area that contacts wafer surfaces is optically polished to reduce surface particles.

These wands are available in virgin PEEK for low particle emission and chemical compatibility, conductive PEEK for ESD protection, and polyphenylene sulfide (PPS). The manual wands, or tweezers, are constructed without glue or metallic parts and they can withstand up to 130ºC temperature continuously.
