Abstract:
1. An LSI chip testing apparatus, for determining whether an electronic circuit of an LSI chip is satisfactory, comprising: a tester for providing a test signal; and at least one probe operatively connected to the tester, the at least one probe having a coil for inductively transmitting the test signal to the electronic circuit of the LSI chip and inductively receiving a response signal from the electronic circuit of the LSI chip, wherein when inductively transmitting, the probe irradiates a magnetic line of flux toward the LSI chip and thereby becomes inductively coupled with a coil of the LSI chip, which is operatively connected to the electronic circuit, and when inductively receiving a signal from the coil connected to the electronic circuit, the probe generates an electromotive force in response to a change in the magnetic line of flux in the coil of the LSI chip such that the probe detects the response signal from the LSI chip and wherein the tester determines if the electronic circuit of the LSI chip is satisfactory based on the response signal.
