A thickness of each of the external electrodes may be 50 nm to 2 ?m. The external electrodes may be formed using a barrel-type sputtering method. A ratio t2/t1 may satisfy 0.7 to 1.2, where t1 is a thickness of each connection part and t2 is a thickness of each band part. A ratio t3/t1 may satisfy 0.7 to 1.0, where t3 is a thickness of each corner part.

The pad fills the trench. The insulating layer includes a passivation layer on the substrate, and a protective layer is on the passivation layer. An etch stop layer is absent between the passivation layer and the protective layer. A vertical level of a bottom face of the trench is higher than a vertical level of one face of the substrate and is lower than a vertical level of a top face of the passivation layer.
