概要（Overview）

EG5/300e and EG4/200e: The EG5/300e, introduced in December 2000, and the EG4/200e, introduced in July 2001, are targeted at the parametric test (“e-test”) segment of the wafer probe market. The EG5/300e, based on the EG5/300, is targeted at the emerging 300mm market. The EG4/200e, based on the EG4/200 platform is for the 200mm market. Both systems incorporate patented technology licensed from partner, Cascade Microtech Inc. This technology allows extremely precise, low-level electrical measurements to be made at the wafer level. This type of electrical measurement performance is becoming increasingly critical for advanced sub-micron semiconductor processes.
