摘要： A plurality of bare semiconductor IC chips are mounted on a base substrate. The base substrate and IC chips are sealed in a package to constitute a multichip module. Diodes are disposed on the base substrate so that an end of each diode is connected to a terminal for connecting each IC chip with said base substrate and the other end thereof is connected to a prescribed voltage. As a result, it is possible to inspect the base substrate by contacting probes only with a connecting pad between the base substrate and a package, to reduce the number of pins of a probe card, to produce a cheap probe card and to reduce a rate of imperfect contact between the probe card and an inspecting pad.

摘要： An apparatus for testing a semiconductor integrated circuit includes a plurality of probe lines and a plurality of sense lines which intersect each other to thereby define a plurality of intersections thereby as electrically isolated from each other. An electronic switch device is provided for each intersection for producing a multilevel signal, on an associated sense line, having one of a predetermined number of voltage levels corresponding to various combinations definable by a predetermined number of binary numbers supplied to test points from logic elements to be tested.In a four test point embodiment, four test points are arranged such that each test point is located in a corresponding one of four quadrants defined by a pair of probe and sense lines intersecting each other. Preferably, the integrated circuit is in the form of a gate array.
