Abstract
A method and system for probing with electrical test signals on an integrated circuit specimen using a high resolution microscope positioned for observing a surface of the specimen exposing electrically conductive terminals thereon. A housing is provided with a carrier therein for supporting the specimen in relation to the microscope and a probe assembly is positionable on the surface of the specimen for conveying and acquiring electrical test signals to and from the specimen. A drive system is provided for shifting at least one of the probe and the carrier to a predetermined test position. In one form the system has a heat shield for protecting one of the probe assembly and the carrier from heat energy generated upon operation of the drive system, and in another form, the system has an environmental control for maintaining a desired temperature within the housing so that accurate measurements may be taken from the specimen.
