Abstract
A pad connection structure includes a substrate, a lower insulation layer formed on a top surface of the substrate, a pad electrode disposed on the lower insulation layer, and an upper insulation layer including an opening through which a top surface of the pad electrode. A step height via the opening is reduced by the lower insulation layer so that connecting reliability with a conductive connection structure is improved.
