Abstract:
1. A method of manufacturing 3D circuit device, comprising the steps of: forming a base by injection molding a first non-conductive material; forming at least one first support, a circuit pattern section, and at least one conducting junction on the base by injection molding a second non-conductive material, such that the at least one first support and the at least one conducting junction are electrically connectable to the circuit pattern section; forming an interface layer to cover the at least one first support, the circuit pattern section, and the at least one conducting junction; forming an insulating layer to cover a portion of the interface layer that is located on the at least one conducting junction; forming a metal coating to cover a portion of the interface layer that is located on the circuit pattern section; removing portions of the interface layer and the insulating layer that are located on the at least one conducting junction; and removing the at least one first support from the base to obtain a 3D circuit device.
