Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first conductive layer over a semiconductor wafer on which a plurality of integrated circuits are formed so that the first conductive layer is electrically connected with electrodes of the semiconductor wafer; forming one or more posts on the first conductive layer by discharging drops of a solvent containing fine particles of a conductive material; forming an insulating layer so that at least a part of the insulating layer is disposed on the first conductive layer; forming a second conductive layer so that at least a part of the second conductive layer is disposed on the insulating layer over the first conductive layer; and cutting the semiconductor wafer, wherein each of the first and second conductive layers is formed by discharging drops of a solvent containing fine particles of a conductive material, wherein the insulating layer is formed by discharging drops of a solvent containing fine particles of an insulating material, and wherein the insulating layer is formed to avoid a region in which the posts are formed.
