Abstract
An improved manufacturing method of a semiconductor device is provided. The method includes preparing a semiconductor substrate having an integrated circuit together with connection pads. The method also includes forming a dielectric film on the semiconductor substrate. The method also includes forming connection wires having a predetermined pattern on the dielectric film such that the connection wires are electrically connected to the connection pads. The method also includes forming a surface resin layer to partially cover the connection wire. The method also includes forming a metal film over the exposed connection wires. The method also includes forming a display unit having through holes to present identification information in a region corresponding to the center area of the semiconductor substrate on the surface resin layer. The forming of the metal film and the forming of display unit are carried out simultaneously.
