Semiconductor device and method of manufacturing the same

摘要

In a semiconductor device (10), plural diffusion layer areas (2, 3) are formed so that the impurity concentration of the diffusion layer area (2) is set to be higher than that of the diffusion layer area (3), and a first contact wire (4) connected to the diffusion layer area (2) having the higher impurity concentration is set to be larger in sectional area than a second contact wire (5) connected to the diffusion layer area (3) having the lower impurity concentration.
