STS Ships VPX Pegasus to Semefab

- VPX System to be Used for Demonstrating Volume Production of UK Nano/MEMS Products

NEWPORT, Wales, July 17 / / - Surface Technology Systems plc (STS) today announced that they have sold a VPX Pegasus system to Semefab, a Scottish-based semiconductor company who specializes in the design and manufacture of silicon IC and MEMS devices.

Semefab, established in 1986, hosts a GBP15 million "open access" centre offering companies from the UK and overseas access to a fully integrated micro and nano-technology capability, from product design and prototyping to product development and testing. The centre is a key part of the UK Department of Trade and Industry's GBP90m Micro and Nanotechnology Manufacturing Initiative launched by science minister Lord Sainsbury in 2003, and is designed to provide a platform to bridge the gap between prototyping and production.

The VPX Pegasus tool provides a production-proven cluster platform twinned with the Pegasus plasma source which offers the higher silicon etch rates and cross-wafer uniformity than conventional de-coupled plasma sources - important factors in increasing throughput and device yield in volume production.

Ian McNaught, MEMS Business Manager of Semefab explained, "We chose the VPX Pegasus to provide us with a market-leading system to demonstrate a wide range of silicon MEMS devices developed by our customers, and also offer an effective foundry service. The Pegasus' high etch rate and the willingness of STS to work closely with the Semefab team are key factors that shall allow Semefab to offer our customers high quality, cost effective process development and fabrication."

John Saunders, CEO of Surface Technology Systems plc, stated, "We are very happy to have this opportunity to work with Semefab to enhance the UK's presence in Micro and Nanotechnology. We will continue to provide world-class wafer processing capability for these exciting applications to all our customers across Europe, America and Asia."
