摘要： There is a need to improve reliability of the semiconductor device.
A semiconductor device includes a printed circuit board and a semiconductor chip mounted over the printed circuit board. The semiconductor chip includes a pad, an insulation film including an opening to expose part of the pad, and a pillar electrode formed over the pad exposed from the opening. The printed circuit board includes a terminal and a resist layer including an opening to expose part of the terminal. The pillar electrode of the semiconductor chip and the terminal of the printed circuit board are coupled via a solder layer. Thickness h 1 of the pillar electrode is measured from the upper surface of the insulation film. Thickness h 2 of the solder layer is measured from the upper surface of the resist layer. Thickness h 1 is greater than or equal to a half of thickness h 2 and is smaller than or equal to thickness h 2 .
