Abstract
A semiconductor device includes a semiconductor chip having a first face and a second face on an opposite side to the first face, and including semiconductor elements arranged on the first face. Columnar electrodes are arranged above the first face, and electrically connected to any of the semiconductor elements. A first member is located around the columnar electrodes above the first face. An insulant covers the columnar electrodes and the first member. The first member is harder than the columnar electrodes and the insulant. The first member and the columnar electrodes are exposed from a surface of the insulant.
