Research Abstract

This research aims to establish a method for room temperature bonding in ambient gas as a new approach to industrial and volume production for devices using the surface activated bonding method which has been developed in advance in Japan.
For thie purpose, the fundamental knowledge for bonding and it mechanism was accumulated and compiled systematically. Based on those research results, new processes including Ar-ion bombardment, Si-nano adhesion layer, atom diffusion bonding, air-plasma treatment, hydrogen radiacal treatment, and their combined process were proposed to demostrate the feasibility of the method for room temperature bonding. During the research also a new finding was done that shows the possibility of bonding polymers, glasses, and SiC using Si-Fe nano-adhesion layer, which was not planned in the original research proposal. Finally it has been shown that the proposed process can be applied successfully to integrating optical microsystems and sealing micro-devices.
