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.

A semiconductor device having a semiconductor chip bonded to the surface of a solid body (another semiconductor chip or wiring board). A hollow enclosed space surrounding a connection member is formed between the solid body surface and the surface of the semiconductor chip opposite thereto. The enclosed space may be formed by a surrounding wall disposed around the circumference of the semiconductor chip. The enclosed space may alternatively be formed by an encapsulating resin for packaging.
摘要:
A production process for a semiconductor device having a metal electrode on a semiconductor substrate thereof. A metal electrode portion is formed on a surface of another substrate for electrode transfer. Then, the metal electrode portion is transferred from the electrode transfer substrate onto the semiconductor substrate by pressing together the electrode transfer substrate and the semiconductor substrate. The electrode transfer substrate has, for example, a seed film provided on the surface thereof, and the formation of the metal electrode portion on the electrode transfer substrate may be achieved by depositing a material for the metal electrode on the seed film by plating. The electrode transfer substrate may have an insulating film which covers a surface of the seed film except a portion thereof on which the metal electrode portion is to be formed.
