  • Patent number: 12341024
    Abstract: According to one embodiment, a method for manufacturing a semiconductor device includes placing a semiconductor chip on a first surface of a support substrate, forming a first resin layer covering the semiconductor chip on the first surface, and forming a second resin layer on a second surface of the support substrate. The second surface is opposite the first surface. In some examples, the second resin layer can be formed to counteract or mitigate warpage of the support substrate that might otherwise result from use of the first resin layer.
