  • Patent number: 12270852
    Abstract: The present disclosure provides a method and a system for testing semiconductor device. The method includes the following operations: energizing an integrated circuit (IC) on a wafer by raising a voltage of the IC to a first voltage level during a first period, and applying to the IC a stress signal including a first sequence and a second sequence during a second period subsequent to the first period, each of the first sequence and the second sequence having a ramp-up stage and a ramp-down stage. The stress signal causes the voltage of the IC to fluctuate between a second voltage level and a third voltage level, wherein a duration of the first sequence is longer than that of the second sequence.
