摘要:
A circuit substrate having a mounting surface on which a semiconductor chip is mounted and at least one connection pad formed on the mounting surface is connected to a support plate having at least one mounting portion with a diameter larger than a diameter of the connection pad, through a truncated-cone-shaped solder layer which is formed from at least one solder ball on the basis of a difference between the diameter of the mounting portion and the diameter of the connection pad.
