Abstract

This paper presented a room temperature bonding technique based on copper nanowire. A structure with copper nanowire array growing on the patterned areas of the silicon substrate was prepared through template-assistant electro-deposition. Through pressing the tilted and straight nanowire arrays against each other, the van der Waals interactions between the interconnected nanowires resulted in the mechanical bonding and electrical connectivity. This room temperature bonding technique exhibited anisotropic adhesion properties. The maximum adhesive strength of 9.36 N/cm2 and electrical resistance of 0.3 (areas, A3.14 mm2) were obtained. Hence, it might have important implications for the assembly of components in the micro electronics.
