摘要：
A semiconductor device with high reliability and operation performance is manufactured without increasing the number of manufacture steps. A gate electrode has a laminate structure. A TFT having a low concentration impurity region that overlaps the gate electrode or a TFT having a low concentration impurity region that does not overlap the gate electrode is chosen for a circuit in accordance with the function of the circuit.
