    摘要: A semiconductor device has a semiconductor substrate having a peripheral circuit area and a memory cell area. A border region having a well of a first conductivity is formed between the peripheral circuit area and the memory cell area. A well of a second conductivity is formed in the peripheral circuit area. The well in the peripheral circuit area is in contact with the border region but not in contact with the memory cell area. Dummy transistors are formed in the border region. The dummy transistors are arranged with substantially the same transistor forming density as that of the memory cell area.
