focuses on low voltage amplifier technology for medical applications, low
power delta-sigma converter design, and ASIC solutions for the medical
electronics device market. Customers include manufacturers of hearing aids,
implantable devices and portable glucose monitors.
AMIS itself counts among its customers a number of medical device producers
including GE Medical, Abbott Labs, Medtronic, Guidant and Siemens.

operation has been transferred to OpNext. The Opto-Device division designs,
manufactures, and sells devices and modules for the access communication,
fibre optic backbone and metro markets, in addition to the information and
industrial markets. The operation's technology base in lasers includes high
power components for DVD applications, receivers and packaging.

inTEST has bought German company Intelogic Technologies, a producer of
docking systems, test head positioners, and other mechanical and automated
equipment for the semiconductor production industry.

unaffiliated company formed to acquire the semiconductor business. The deal
was worth $700,000 in cash plus future royalties. The maximum worth of the
deal could be $1.9mn, if the acquirer were to remit the full amount of
