Abstract: PURPOSE:To enable a high-accuracy alignment by a method wherein, of longitudinal and lateral dimensions of the plane of each pad, one is set to be larger than the other. CONSTITUTION:Elliptic pads 12 are arranged on the same axial line to the center O of a semiconductor chip 13 and the configuration of each pad 12 has a form that the width (w) seen from the direction of the center O of the chip 13 has a proportionality of w:d=x:1 (x>1) and is enlarged to the depth (d). That is, the dimension on the side of one side of the plane longitudinal and lateral dimensions of each elliptic pad 12 is set in a dimension larger than that on the side of the other side. In such a way, as each projection surface area S0 of solder connectors 14 is enlarged to the external force in any direction compared with each projection surface area S1 of solder connectors 14a on circular pads 12a, a disturbance energy can be stopped by the large surface areas of the connectors 14 compared with the case where the solder connectors 14a are used on the circular pads 12a of the same plane aspect ratio. Thereby, the alignment accuracy of a substrate 11 to the chip 13 can be improved.
