Abstract:
1. A semiconductor device, comprising: a circuit board having an element mounting area, connecting pads positioned in the same surface side as said element mounting area and external connectors to be connected with the said connecting pads, respectively; and a semiconductor element mounted on said element mounting area of said circuit board and having electrode pads to be electrically connected with said connecting pads, respectively, wherein said external connectors are detachably configured through a combination of convex portions and concave portions which are mechanically and electrically connected with one another, and each of said external connectors is embedded into said circuit board and includes at least one of a convex connector corresponding to said convex portion and a concave connector corresponding to said concave portion, the convex connector having a first inverted truncated cone form having a first circular top, a first circular bottom, and a circular body which tapers, a diameter of the first circular top being larger than that of the first circular bottom, and the concave connector having a second inverted truncated cone form having a second circular top, a second circular bottom, and a circular inner side which tapers, a diameter of the second circular top being larger than that of the second circular bottom, corresponding to the first inverted truncated cone form.
