A component ACF (150a) made of a single sheet is used to further mount discrete electronic components such as stabilizing capacitors (150) on the glass substrate (110). The component ACF (150a) has a size that covers not only a region where the discrete electronic components are to be mounted, but also the top surfaces of the LSI chip (130) and the FPC board (140) which are mounted first. By thus using the large component ACF (150a), a positional constraint upon adhering the component ACF (150a) to the glass substrate (110) is eliminated, reducing the area of a region where the discrete electronic components are mounted. By this, a board module miniaturized by reducing the area of a region where discrete electronic components are mounted is provided.

  • Patent number: 7919875
    Abstract: A manufacturing method of a semiconductor device formed in a chip size package is improved to enhance a yield and reliability. A window to expose first wirings is formed only in a region of a semiconductor substrate where the first wirings exist. As a result, area of the semiconductor substrate bonded to a supporting body through an insulation film and a resin is increased to prevent cracks in the supporting body and separation of the semiconductor substrate from the supporting body. A slit is formed along a dicing line after forming the window, the slit is covered with a protection film and then the semiconductor substrate is diced into individual semiconductor dice. Thus, separation on a cut surface or at an edge of the semiconductor dice, which otherwise would be caused by contact of the blade in the dicing can be prevented.
