Abstract: A method, apparatus and computer program product for testing semiconductor products that combines multiple techniques. Depending on the requirements, different ones of the techniques are emphasized over the other techniques. The testing applies a technique to achieve a higher single defect acceleration parameter at the expense of a second parameter, thus enabling acceleration of defects that require higher voltage or higher temperature than a traditional “Burn In” can achieve, which defects would otherwise go unaccelerated. The method manages the adaptation of the different techniques, e.g., how it decides to favor one technique over the other, and how it carries out the favoring of one or more particular techniques in a given test situation. Thus, acceleration to defectivity (defect type and quantity) may be tailored in real time by uniquely leveraging the duration spent in a given section of a process flow based on the prevalence of unique defect types.

Abstract: A test fixture has a flexible plastic cable that acts as a waveguide. The Device-Under-Test (DUT) is a small transceiver and antenna that operate in the Extremely High-Frequency (EHF) band of 30-300 GHz. The size of the DUT transceiver is very small, limiting the power of emitted electromagnetic radiation so that close-proximity communication is used. The envelope for reception may only extend for about a centimeter from the DUT transceiver, about the same size as the test socket. A slot is formed in the test socket very near to the antenna. The slot receives one end of the plastic waveguide. The slot extends into the envelope by the DUT transceiver so that close-proximity radiation is captured by the plastic waveguide. The waveguide has a high relative permittivity and reflective metalized walls so that the radiation may be carried to a receiver that is outside the envelope.
