ABSTRACT:
A semiconductor memory device has a memory cell area and a peripheral area including a scribe area. A large number of first monitoring patterns are disposed in the scribe area for monitoring the peripheral circuit in the peripheral area, whereas a few number of second monitoring patterns are disposed adjacent to the memory cell area for monitoring the characteristics of the memory cells. A CMP process which reduces the thickness of the memory device does not generate dust of the conductive material from the scribe area because the first monitoring pattern has a level substantially equal to the level of the peripheral area.
