Semiconductor construct and manufacturing method thereof as well as semiconductor device and manufacturing method thereof

摘要

A semiconductor construct includes a semiconductor substrate and connection pads provided on the semiconductor substrate. Some of the connection pads are connected to a common wiring and at least one of the remaining of the connection pads are connected to a wiring. The construct also includes a first columnar electrode provided to be connected to the common wiring and a second columnar electrode provided to be connected to a connection pad portion of the wiring.
