Abstract
A semiconductor device is provided with circuit patterns and dummy patterns. The circuit patterns facilitate circuit operations and the dummy patterns do not facilitate circuit operations. The dummy patterns are formed as patterns at which crystal defects are more likely to be caused by stress than the circuit patterns.
