METHOD OF MOUNTING SEMICONDUCTOR CHIPS, SEMICONDUCTOR DEVICE OBTAINED USING THE METHOD, METHOD OF CONNECTING SEMICONDUCTOR CHIPS, THREE-DIMENSIONAL STRUCTURE IN WHICH WIRING IS PROVIDED ON ITS SURFACE, AND METHOD OF PRODUCING THE SAME

摘要

A method of mounting a semiconductor chip includes: forming a resin coating on a surface of a path connecting a bonding pad on a surface of a semiconductor chip and an electrode pad formed on a surface of an insulating base material; forming, by laser beam machining, a wiring gutter having a depth that is equal to or greater than a thickness of the resin coating along the path for connecting the bonding pad and the electrode pad; depositing a plating catalyst on a surface of the wiring gutter; removing the resin coating; and forming an electroless plating coating only at a site where the plating catalyst remains.
