摘要:
An apparatus and a method for testing semiconductor devices such as integrated circuits having a handler for picking up an integrated circuit to be tested and placing the picked up integrated circuit into an automatic circuit test apparatus. When the circuit to be tested is inserted into the test apparatus an extraneous signal shield is automatically engaged to enclose the device being tested and protect the circuit, being tested, from stray extraneous electromagnetic signals during the test thereby preventing said stray electromagnetic interference from inducing errors in the tested circuit.
摘要:
A semi-conductor module burn-in test apparatus having a plurality burn-in boards each of which is provided a plurality of module test sockets thereon and each test socket is coupled to an adjacent test socket by with a high current, open/short split power connector that can readily connected to or disconnected from said adjacent test socket by coupling together the power inputs of the adjacent sockets or uncoupling the previously coupled power inputs of adjacent sockets and thereby selectively altering the current carrying levels available to said adjacent test sockets.
摘要:
A method is described by which the mechanical strength of chips of semiconductor devices can be controlled by appropriate wafer finishing and sorted by knowledge of the finishing method and chip and wafer geometry. The control and sorting derive from a knowledge of the geometry of the striations remaining on the back of chips after the wafer-grinding finishing step.
