    Abstract: A semiconductor device with a multi-tier construction includes a first tier having a first die, a second die spaced apart from the first die in a first direction and a fill material therebetween. A second tier overlays the first tier, and includes a bridge die partially overlaying the fill material and the first and second dies. The bridge die provides an electrical interconnection between the first and second dies in the first tier. The device also has a first protective structure aligned with a first interface between an end of the first die and the fill material that includes a first part formed on a first side of the first die at the end of the first die; and a second part formed on a first side of the bridge die. The first and second parts are aligned and form the first protective structure, mitigating cracking near the bridge die.

    Abstract: The present disclosure provides a method and a system for testing semiconductor device. The method includes the following operations. A wafer having an IC formed thereon is provided. The IC is energized by raising the voltage of the IC to a first voltage level during a first period. A stress signal is applied to the IC. The stress signal includes a plurality of sequences during a second period subsequent to the first period. Each of the sequence has 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. Whether the IC complies with a test criterion is determined after applying the stress signal.

    Abstract: The present disclosure provides a method and a system for testing semiconductor device. The method includes providing a device under test (DUT) having an input terminal and an output terminal; applying a voltage having a first voltage level to the input terminal of the DUT during a first period; applying a stress signal to the input terminal of the DUT during a second period subsequent to the first period; obtaining an output signal in response to the stress signal at the output terminal of the DUT; and comparing the output signal with the stress signal. The stress signal includes a plurality of sequences, each having a ramp-up stage and a ramp-down stage. The stress signal has a second voltage level and a third voltage level.
