Abstract:
A test system for testing semiconductor elements formed on a semiconductor wafer, comprising:an aligner for bringing three components into contact with one another to form a one-body structure, said three components being a wafer holder member used for holding a semiconductor wafer, a semiconductor wafer having a plurality of semiconductor elements on a surface, and a contactor having a plurality of contact terminals to be brought into electric contact with electrodes of the semiconductor elements, said one-body structure being used as a test shell,said aligner including:a shell assembling mechanism for forming the test shell by vacuum suction;a first read device for reading a shell identification code attached to the test shell;a first storage device for storing the read shell identification code; anda first control device for controlling the shell assembling mechanism to form the test shell;a test apparatus for executing a test with respect to the semiconductor elements of the test shell,said test apparatus including:a second read device for reading the shell identification code attached to the test shell; anda second storage device for storing results of the test in association with the shell identification code; anda transmission system for enabling information stored in the first and second storage devices to be exchanged between the aligner and the test apparatus.
