    摘要: A high performance test head (18) communicates test signals between integrated circuit test pads and integrated circuit tester. Test head (18) comprises metal bumps (22) that electrically couple with test pads to communicate test signals between test pads and test circuitry. Planar foundation plate (30) provides structural support. Compliant material layer (26) associates with metal bumps (22) and compresses to assure positive contact between metal bumps (22) and test pads. Compliant material layer (26) is positioned between foundation plate (30) and metal bumps (22). Interconnection line (20) adjoins test head (18) to connect metal bumps (22) between test circuitry and integrated circuits. The present invention includes a method for high performance communication of test signals between test pads and test circuitry. The present invention further includes the method of applying semiconductor device fabrication techniques to produce a high performance test head (18).

    摘要: A dynamic MOS read/write memory has a substrate bias generator circuit which includes, in this example, four separate pump circuits. A first of these operates only during power-up to quickly produce the desired back bias; this pump circuit uses a high frequency oscillator and a low impedence drive, and cuts off to save power as soon as the necessary bias is reached. A second generates a smaller sustaining current, using a lower frequency oscillator and higher impedance drive; this functions to compensate for leakage during idle periods. The third and fourth pump circuits are driven by RAS and CAS, so these occur only when needed, and at a rate dependent upon the actual operating condition of the memory.
