Patent ID: 8704106

Claim:
A method of manufacturing an electronic component comprising: forming a resin layer over an underlying layer; pressing a conductor plate having a pattern formed on one major surface thereof against the resin layer, and embedding the pattern in the resin layer; and performing polishing, Chemical Mechanical Polishing, or cutting by the use of a diamond bit on another major surface of the conductor plate until the resin layer appears, and leaving the pattern which is pressed against the resin layer and embedded in the resin layer as a conductor pattern, wherein, in the leaving the conductor pattern in the resin laxer a first portion and a second portion are formed in the conductor pattern, the second portion being thicker than the first portion, and the method further comprises bonding a protrusion electrode which includes a low melting point metal to the second portion of the conductor pattern after the conductor pattern is left in the resin layer.
