摘要:
A connection structure (package 10) has a first plate body 101 and a second plate body; in the first plate body 101, a wiring pattern having a plurality of connection terminals 102 is formed, and the second plate body has at least two connection terminals (electrode terminals 104) arranged facing the connection terminals of the first plate body 101. The connection terminals of the first and second plate bodies are connection terminals formed as projections on the surfaces of the first and second plate bodies. A conductive substance 108 is accumulated to cover at least a part of each side face of the connection terminals opposed to each other of the first and second plate bodies, and the connection terminals thus opposed are connected to each other via the conductive substance. The package thus formed is ready for a high-pin-count, narrow-pitch configuration of a next-generation semiconductor chip, and exhibits excellent productivity and reliability. The present invention is advantageous for such a package, for a connection structure applicable to the production of the package, and for a method of producing the connection structure.
