The longitudinal die is configured as a longitudinally cut-away forming orifice from a surface of the substrate. The lateral mold is configured to form lateral grooves cut laterally from the sides of the substrate. The combination of the lateral groove and the aperture is the complex concave structure mentioned in S113. Similarly, a complex convex structure is fabricated on the surface of the substrate by combining another combined die with a bump which is directly fixed on the substrate and can be used as a part of the substrate.
