Abstract (en)

[origin: WO9956137A1] Method and apparatus for testing interconnect networks, by generating at least two plasma jets, each in the vicinity of a distinct point (12, 13) of the circuit to be tested, applying a voltage difference whereby to cause an electric current to flow between the points through the circuit, to each point through the corresponding plasma jet and maintaining the current flow to carry out the testing process. Each plasma jet is generated by producing a discharge between two electrodes within a cavity, said plasma being ejected out through an orifice. The apparatus comprises at least two plasma injector-electrodes (14, 16) to drive an electric current between two points of the circuit to be tested, each so positioned or positionable as to direct the plasma generated thereby to one of the two points, a first electric circuit (21, 27) to supply voltage to each plasma injector-electrode, means (18, 20) for supplying gas to each plasma injector-electrode, and a second electric circuit (21, 27) similar or different from the first electric circuit, to sustain electric discharge.
