Abstract
A method of testing unpackaged integrated circuits using a tester which is capable of testing a plurality of memories in parallel is provided. A membrane test head having a plurality of probe bumps thereon is provided wherein the probe bumps are coupled to the tester by microstrip transmission lines formed on the membrane test head. The semiconductor memory has a plurality of contact pads thereon which are coupled to the probes. In this manner, a plurality of semiconductor memories can be tested in wafer form. Alternatively, individual semiconductor memory chips can be mounted on a receiver plate and tested individually or in parallel by moving the receiver plate so that the contact pads couple to the probes.
