Motorola Inc describes as unprecedented an agreement between its Application Specific Integrated Circuits division and the Automated Test Equipment division of Schlumberger Technologies a business that the Franco-American oilfield services firm has put on the block: the new pact provides for development of semiconductor tester technology and delivery of five of the new test systems to Motorola from third quarter of 1990, following a prototype in October of this year; the initial agreement is valued at more than $8m but will have much broader ramifications through its ultimate impact on the estimated $625m worldwide digital component test equipment market, they reckon.
