Abstract :
Multilayer polyimide (MLP) structures are discussed. Recently, a low-mechanical-stress, low-dielectric-constant polyimide material has become commercially available. It can be processed using standard integrated-circuit (IC)/hybrid technologies and equipment. The material is ideally suited for use in high-density multilayer interconnect structures. The processing of thick (18-μm) polyimide layers with buried metal layers is described. Applications of single-layer and multilayer polyimide structures can be designed into existing packaging products as an enhancement or be used as an added packaging structure for high-performance devices
