Patent JP-2001249147-A (JP)
Title: Circuit and method for detecting current
Inventor: GOTO JUNICHI
IPC: G01R31/02
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To solve the problem with a conventional current detection method that measuring microcurrents in an element in an LSI with a parameter analyzer requires a connection pad of about 100 micron angles for connecting the element with the parameter analyzer, leading to difficulty in arranging a sufficient number of elements to obtain the in-wafer distribution of element characteristics which are important data for the development and improvement of a device. SOLUTION: A capacitance 1 is chargedby conducting a switching means 2 and is discharged via an element to be measured, by shutting off power to the switching means. A voltage comparison means 3 detects that the voltage of the capacitance 1 becomes lower than a reference voltage Vr, and then transmits an output to a comparison result V0. The greater the discharge current, the shorter the time needed for the voltage of the capacitance 1 to become lower than the reference voltage Vr, so evaluation on the magnitude of the current is made based on the length of drop time. All inputs and outputs are made by an LSI tester whereby it is possible to measure currents which cannot be measured with the LSI tester alone.
