Abstract
In this chapter, we outline the revolution of wafer bonding technologies in microelectromechanical systems (MEMS) packaging and their applications in the emerging field of micro/nanofluidics-enhanced sensing. With the rapid development of device miniaturization, high-density assembly technologies have become one of the most important research topics in three-dimensional (3D) integration. The role of packaging has also shifted from initial physical protection and electrical interconnection to a multifunctional platform and/or interfaces. Hence, wafer bonding-based packaging technologies also benefit from diversified applications, e.g., micro/nanofluidics, optoelectronic integration, and biological/chemical sensing. Based on the aforementioned aspects, we summarize the development of wafer bonding technology to enable researchers to know the recent progress of homo−/heterogeneous integration.
