Abstract

PURPOSE:To measure an element at high speed by editing a program for measurement and a test pattern in response to positional coordinates on a wafer. CONSTITUTION:A measurement start signal is transmitted over a measurement starting control section 32 in a tester 3 from a measurement starting signal generating section 22 in a prober 2. Consequently, a positional coordinate signal from a positional coordinate generating section 21 in the prober 2 is read by a positional coordinate recognizing section 31 in the tester 3. A measurement program editing section 35 in the tester 3 edits a program for measuring an integrated circuit element to be measured in a wafer 1 through corresponding with an editing table 36. When there is no program edited by the editing table 36 in high-speed processing containing sections 37, 38, a program for measurement and a test patter from a large capacitance containing section 39 are transferred to the high-speed processing containing sections 37, 38. A probe card 24 in the prober 2 is brought into contact with the integrated circuit element on the wafer 1, and a program for measurement from a measuring section 34 is transferred to the element 1 on the wafer 1 through the probe card 24. When measurement is completed, the measuring section 34 transmits the results of measurement over a measurement-result processing section 33.
