X-FAB to Present Free ''Lunch & Learn'' Technical Seminar.

X-FAB Semiconductor Foundries:

WHO:    X-FAB Semiconductor Foundries, a leading analog/mixed-signal
        semiconductor foundry manufacturing silicon wafers for analog-
        digital integrated circuits (mixed-signal ICs) on customer
        order. The company maintains wafer production facilities in
        Erfurt (Germany), Plymouth (UK) and Lubbock, Texas (US), and
        employs approximately 1,100 people worldwide. It manufactures
        wafers based on ultra-modern modular CMOS and BiCMOS processes
        with technologies ranging from 1.0 down to 0.35 micron. Main
        application areas include the automotive, communications,
        consumer and industrial sectors.

WHAT:   X-FAB's informative, free seminar will explore how to make use
        of unprecedented circuit design possibilities in mixed-signal
        CMOS technologies, and how process control monitoring ensures
        consistent quality. A presentation by Alexander Hoelke, Ph.D.,
        Intelligent solutions for complex mixed-signal designs using
        X-FAB's new modular trench-isolated 0.6 micrometer SOI CMOS
        technology, highlights the advantages of X-FAB's latest
        process technology with dielectric isolation for unrestricted
        low- and high-side operations of all devices up to 60 V. It
        explores reduced parasitics, small crosstalk and improved
        electro-magnetic compatibility (EMC), and examines innovative
        circuit solutions such as CMOS integrated diodes in forward
        and reverse operation mode. A presentation by Steffen Richter,
        From Process Development to Process Control Monitoring (PCM):
        How does X-FAB ensure consistent wafer quality? investigates
        what happens when the world of process specification meets the
        world of real silicon. It examines PCM test structures and
        their use, and discusses X-FAB's PCM test strategies to
        achieve yield improvements.
