Automatic test equipment platform architecture using parallel user computers

摘要

The present invention provides a system of testing semiconductor devices. The system comprises a central host computer, an array of user computers (the array), and a HU (Host-User) network as the mean of communication between them. Two user computers are dedicated to one test instrument via UI connections in the instrument test head, a first user computer can be assigned to perform the tasks of generating and delivering data to the test instrument, while a second user computer can be assigned to perform the tasks of receiving and processing information from the same test instrument.
