Abstract
Oppositely arranged bumps ( ) are electrically connected by connecting two IC chips ( ) through an anisotropic conductor ( ) to form an IC chip module ( ). With IC chip module ( ) having such structure, two IC chips ( ) provided with functions of a processing portion and an antenna are simply stacked to provide a function for communication, and arrangement of interconnection outside IC chip ( ) is not necessary. Thus, accidental breakage of the interconnection is avoided and assembly is extremely facilitated. Therefore, a circuit chip mounted card with higher reliability and reduced manufacturing cost and the like can be provided.
