Patent ID: 7937827

Claim:
A method for producing a multilayer substrate, the method comprising: stacking a first substrate, the first substrate having a first circuit pattern; stacking a connector, the connector coupling onto said first substrate, the connector having a ring structure, the ring structure having a plurality of holes separated by a predetermined distance from one another; stacking a second substrate, the second substrate coupling onto said first substrate by inserting said connector therebetween, the second substrate having a second circuit pattern, the second circuit pattern being electrically connected to the first circuit pattern formed on said first substrate, the second circuit pattern being electrically connected using the plurality of holes formed on said connector; and stacking a coupling pin connecting an inside wall of the plurality of holes to the first circuit pattern, the first circuit pattern corresponding to a first signal line formed on said first substrate, wherein said connector further comprises: a body which is made from a conductive material; a dielectric coating only the inside wall of said plurality of holes; and a connecting part comprised of a conductive material coating only said dielectric, wherein a slot is formed in the connecting part, one end of the slot being closed, and the coupling pin fits in the slot.
