Abstract:
A semiconductor wafer testing method using a probe for testing a plurality of semiconductor units formed on a surface of a semiconductor wafer;said semiconductor wafer testing method comprising the steps of:forming a temporary test film on the surface of the semiconductor wafer so as to be detachable therefrom by exfoliation, forming each of said plurality of semiconductor units on said semiconductor wafer being provided with a plurality of semiconductor unit electrodes, and providing said temporary test film with a plurality of regularly arranged test electrodes and wiring patterns for electrically connecting said plurality of regularly arranged test electrodes with corresponding ones of said plurality of semiconductor unit electrodes of said plurality of semiconductor units;testing said plurality of semiconductor units by applying a plurality of probe pins of said probe to corresponding ones of said plurality of regularly arranged test electrodes provided in said temporary test film; anddetaching by said exfoliation said temporary test film from the surface of said semiconductor wafer.
