1. An electronic device, comprising:
a core circuit comprising a plurality of core metal oxide semiconductors (core MOS); and a plurality of pad units, respectively electrically connected to said core circuit, and each pad unit comprising a plurality of pad metal-oxide-semiconductors (pad MOS), wherein the longer dimension of a core gate in each said core MOS and the longer dimension of a pad gate in each said pad MOS all extend in the same direction; wherein said pad unit further comprises an individual N-type metal oxide semiconductor (NMOS) region, an individual pad region and an individual P-type metal oxide semiconductor (PMOS) region, one of said N-type metal oxide semiconductor (NMOS) region, said pad region and said P-type metal oxide semiconductor (PMOS) region of each said pad unit is sandwiched between the other two of said N-type metal oxide semiconductor (NMOS) region, said pad region and said P-type metal oxide semiconductor (PMOS) region of each said pad unit, and said pad metal-oxide-semiconductors are disposed in said pad region and in at least one of said NMOS region and said PMOS region of said pad unit. |
