Fish & Richardson P.C.
Semiconductor device and electronic device
To provide a semiconductor device that is not easily damaged by ESD in a manufacturing process thereof. A layer whose band gap is greater than or equal to 2.5 eV and less than or equal to 4.2 eV, preferably greater than or equal to 2.7 eV and less than or equal to 3.5 eV is provided to overlap with a dicing line. A layer whose band gap is greater than or equal to 2.5 eV and less than or equal to 4.2 eV, preferably greater than or equal to 2.7 eV and less than or equal to 3.5 eV is provided around the semiconductor device such as a transistor. The layer may be in a floating state or may be supplied with a specific potential.
