Three dimensional integration circuits technology has received much attention recently since the demands of functionality and performance in microelectronic packaging for electronic products are rapidly increasing. For high-performance 3D chip stacking, high density interconnections are essential. In the current types of interconnects, solder micro bumps have been widely used and thermocompression...
Recently, three dimensional integration circuits technology has received much attention since the demands of functionality and performance in microelectronic packaging for electronic products are rapidly increasing.

As the demands of functionality and performance for electronic products increase, three-dimensional chip stacking with high-density I/O has received much attention. For high density interconnections packaging, solder micro bumps are adopted extensively. However, its process temperature is high during chip stacking process. High bonding temperature would be easy to lead chip damage and chip warpage...
As the demands for high density 3DIC stacking increase, a fine-pitch chip-to-chip interconnects is becoming imperative. In conventional flip-chip technology, anisotropic conductive film (ACF) has been used in place of solder and underfill for chip attachment to substrates in some applications, because it provides many advantages. Generally speaking, ACF consists of an adhesive polymer matrix with...
Recent developments of nanofabrication have enabled the miniaturization of electronic devices, allowing more electronic devices to be combined into a single device with a high performance. However, the complex devices have led to the escalation of power dissipation as well as the increasing heat flux at the interface between devices. Electronic devices were damaged by much heat accumulation, since...
