Patent ID: 8486759

Claim:
A method for forming a stacked package of a plurality of stacked package elements, each package element having a front face and a side face, the side face having a portion of a connection terminal thereon, the connection terminal being coupled with a circuit pattern formed on the front face, the method comprising: a first step of forming, on each of said stacked package elements, said connection terminal extending at least from the front face to the side face to be coupled with said circuit pattern formed on the front face; a second step of stacking and bonding said plurality of stacked package elements on each of which said connection terminal has been formed; and a third step of interconnecting connection terminal portions on the side faces of said bonded respective stacked package elements by a wiring pattern formed by spraying of a conductive material in a mist state and changing of a position to be sprayed, wherein the angle formed by the front face and the side face is an obtuse angle, and wherein the side faces of the package elements meet to define a unitary planar surface of the stacked package which is inclined relative to a top surface of the stacked package and which extends from the top surface to a bottom surface of the stacked package.
