STC Purchases Mask Aligner to Perform Mask Alignment of 200 mm Wafers

ClassOne Equipment has marketed its 150th mask aligner product to the Smart System Technology and Commercialization Center (STC) which is a division of the College of Nanoscale Science and Engineering (CNSE) at Albany.

For over eight years, ClassOne Equipment has been supplying high-quality refurbished equipment to the MEMS, semiconductor, and advanced technologies markets and has now made a sale of more than 1,500 manufacturing devices to over 500 customers worldwide.

The STC of CNSE was looking out for a mask aligner in the market that had the ability to carry out front-to-back mask alignment of wafers measuring 150 mm and 200 mm to enable expansion of its processing line. The key factors considered by STC in selecting a supplier were lead time, quality, and price.

Paul Tolley, Executive Director of STC and Vice President for Disruptive Technologies at CNSE, stated that since they were expanding from a 150 mm platform to a 200 mm platform, STC found a mask aligner that offers a rare alignment capability ensuring high-precision front-to-back alignment with a superior-level of automation. He added, with the capability to precisely pattern front and back sides of an individual wafer, the inclusion of the SUSS MicroTec MA200 mask aligner will offer support to a wide range of vital applications such as microfluidic devices, bio and chemical sensors, and RFMEMS components.

MEMS start-up companies and fabrication facilities involved in complete production, universities, and research institutes worldwide have acknowledged the quality of ClassOne’s renovated mask aligners. With a huge catalogue of mask aligners from manufacturers such as HTG, ABM, OAI, EVG, and SUSS, ClassOne stocks well-known models that include EVG 620, MA200, MA150, MA6, and MJB3 mass aligner.

Apart from this success in the MEMS equipment and semiconductor market, ClassOne has shown considerable growth in other areas such as KLA-Tencor metrology tools and Semitool wet-processing devices.
