| 摘要 |
A semiconductor device mount structure containing a semiconductor device (10), a connection substrate (30) disposed at the lower side of the semiconductor device (10), and leads (20) which are connected to external connection terminals (12) of the semiconductor device (10) at one end thereof, turned back and connected to wires provided on the connection substrate (30) at the other end thereof. The connection substrate (30) is constructed by plural carrier substrates. Each of the plural carrier substrates is right-angled isosceles triangular, and the plural carrier substrates are arranged so as to form a substantially square shape at the lower portion of the semiconductor device (10). <IMAGE> |
