Metallized Thin Glass WaferAxus Technology (Axus), a leading global provider of CMP, wafer thinning and wafer surface processing solutions for semiconductor applications, is excited to be working with Mosaic Microsystems to build the supply chain for thin glass and through-glass via (TGV) processing and heterogeneous microelectronic packaging. Overcoming the challenges of handling, thinning, and cleaning <200 um thick wafers cost effectively prior to metallization is a key element in providing a robust, scalable process.

Mosaic’s thin glass solutions provide key performance characteristics such as low loss, CTE match, environmental stability, and cost effectiveness particularly desirable for 5G applications, as well as for MEMs and sensors for the internet of things (IoT). The proprietary Viaffirm™ temporary bond technology, uses innovative approaches to support thin glass substrates during downstream processing.  This thin glass handling technology allows the supply chain to leverage the existing infrastructure, thereby unlocking the value that thin glass brings to next generation microelectronics and photonics applications.

Axus’ leading-edge CMP systems and tools help improve the polish performance of thin wafers by utilizing the Axus Crystal carrier, specifically designed for ultra-thin and fragile wafers, along with expert process development from our stellar foundry and development lab. Industry needs for glass wafers are being addressed in a prolific way by the processes that support bonding, debonding, and CMP of thin, fragile substrates.

Dan Trojan, President and CEO of Axus, commented “The development of processes and fragile wafer handling capabilities for thin glass wafers that we’re supporting in our partnership with Mosaic Microsystems is something we’re truly excited about.  We believe this development will result in compelling solutions to difficult challenges in this evolving and growing market.  We and our customers are already deeply involved in these types of applications, as evidenced by several of our recent new product introductions.  These include Crystal wafer carriers, Crystal load stations, and last-but-not-least our new, state-of-the-art CapstoneTM CMP system.  We believe that all of these products are the best solutions available in the industry for these types of materials and applications.”

Aric Shorey, Vice President of Business Development at Mosaic Microsystems, commented “We have been very pleased to work with Axus for our CMP and finishing needs and appreciate how they have seamlessly employed Mosaic’s Viaffirm™ temporary bond technology into their processes and been successful in finishing substrates as thin as 100 um from the start.”
