Abstract:
1. A method for producing a substrate for mounting a device, comprising: preparing a metal plate on one major surface of which a plurality of projected electrodes are provided; forming an insulating resin layer on said major surface so as to cover the top surface of the projected electrodes; exposing the top surface of at least one of the plurality of projected electrodes by removing the insulating resin layer so that a major surface of the insulating resin layer opposite to the metal plate is level; arranging a plurality of counter electrodes having a counterface to face the top face of the plurality of projected electrodes; electrically connecting the at least one of the plurality of projected electrodes, the top surface of which is exposed, with at least one of the plurality of counter electrodes facing the projected electrodes, by pressure-bonding the metal plate with the counter electrode; and forming a wiring layer by selectively removing the metal plate.
