In this study, PI/Cu lap joint specimens were used to investigate the mechanical properties and interfacial adhesion performance of PI under different curing conditions. Through lap shear tests, scanning electron microscopy (SEM) analysis, and finite element method (FEM) simulation, the applicability of PI in packaging structures was systematically analyzed. The results show that PI sintered at high temperature exhibits good structural stability and is less prone to crack formation during deformation. But it has relatively low fracture toughness and strength, and tends to delaminate from Cu, making it unsuitable for structures subjected to large deformations. In contrast, PI cured at room temperature demonstrates higher fracture strength and better interfacial adhesion, as well as greater deformability, but is more prone to crack initiation, making it less suitable for structures under long-term loading.

Self-sustained oscillation is a main obstacle in deeper studying the short-circuit characteristics of cascode GaN devices, in many cases, the device is damaged by the self-sustained oscillations rather than the thermal/electrical stress of short circuits. To avoid the self-sustained oscillations during short circuits, a modified short-circuit test platform is proposed to conduct the short-circuit test safely. To characterize the static performance of the Si and GaN parts separately in a fair way, a new decapsulation method without affecting the die performance is proposed on a commercial cascode GaN device. Considering the trap effect on GaN devices, a fair test procedure is designed to avoid the influence brought by the fluctuation of the GaN threshold voltage. In the end, the performance degradation is analysed after going through repetitive short-circuit tests under 100 V/10 μs.
