Abstract
A semiconductor device includes a circuit pattern on a substrate, a shielding pattern on the circuit pattern and constituted by a plurality of parallel bars, and lower overlay marking on the shielding pattern and constituted by a plurality of parallel bars which define parallel slits between the bars. The pitch of the bars of the shielding pattern is smaller than the pitch of the bars of the lower overlay marking.
