Abstract
A semiconductor chip in which a through hole penetrating through its surface and reverse surface is formed in a scribe line region in the vicinity of an active region where a functional device is formed, and a conductive member is arranged in the through portion. The through portion may be a groove opening sideward on a sidewall surface of the semiconductor chip. The through portion may be a through hole blocked from a side part of the semiconductor chip. The semiconductor chip may further include wiring for electrically connecting an internal circuit formed in the active region and the conductive member to each other.
Claims16
A semiconductor chip, wherein
- a through portion penetrating through a surface and a reverse surface of the semiconductor chip is formed in a scribe line region in the vicinity of an active region where a functional device is formed, and a conductive member is arranged in the through portion.
