제목 The Effects of Imidization History and Thermal Cycling on the Residual Stress Behavior of Transparent Polyimide Nanocomposites
초록 The current trend in the interconnect development is to incorporate polymer layers together with glass, organic or ceramic layers to form a multilayered devices. One of the most important concerns is the mechanical integrity of the multilayered structures. For multilayered device, there are often reliability problems, such as displacement, cracks, and delamination at interfaces. Thermal stress causes interfacial adhesion and mechanical failures associated with interfacial residual stress due to the mismatch of physical properties between polymers and the other materials used. For this study, a computer-controlled experiment has been set up to measure the thermal stress of multilayered films using the bending wafer technique. To understand and classify these phenomena, the bending beam technique for thermal stresses kinetics according to imidization history and thermal cycling in PI nanocomposite thin films prepared from various OMMT nanoparticles were used.
