Abstract:
A measuring method of an integrated circuit structure including at least one coil comprising a plurality of turns for detecting a short-circuit between turns of said coil, wherein said method comprises the following steps:measuring a first and a second resistance across first and second portions of said coil, corresponding to two different numbers of turns of the coil, via contact pads integral with said turns on the first and second portions and four tips of a resistance measuring machine;computing the ratio of said first and second resistances measured across the terminals of first and second portions of said coil;comparing said ratio to a constant corresponding to a ratio of resistance measurements made on coils of identical geometry; anddetermining the presence or the absence of a short circuit between at least two turns of one of said portions of said coil, when the ratio is different from or respectively equal to said constant.
