发明名称 Method of testing electrical characteristics of multiple semiconductor integrated circuits simultaneously
摘要 A method of testing semiconductor integrated circuits comprises the step of simultaneously testing a plurality of semiconductor integrated circuit elements for electric characteristics by applying a voltage to the respective testing electrodes of the semiconductor integrated circuit elements. The simultaneous testing step includes the step of applying the voltage to the respective testing electrodes of the semiconductor integrated circuit elements via PTC elements provided for the semiconductor integrated circuit elements in a one-to-one relationship.
