Abstract
(EN) The present technology relates to: a semiconductor device enabling to suppress breakage of a side wall insulating film due to charge damage, and to suppress a short-circuit that could have been occurred between a semiconductor substrate and a through electrode; a method for manufacturing the semiconductor device; a solid-state image pickup element; and an electronic apparatus. The semiconductor device according to one aspect of the present technology is provided with: a first semiconductor substrate, in which a predetermined circuit is formed; a second semiconductor substrate bonded to the first semiconductor substrate; and a through electrode that electrically connects the first semiconductor substrate and the second semiconductor substrate to each other. The through electrode is formed by opening a through hole by penetrating a protection diode structure formed in the first semiconductor substrate, depositing an insulating film on the side wall of the through hole, and applying an electrode material to the inner side of the through hole on which the insulating film is deposited. This technology can be applied to, for instance, CMOS image sensors.

Selon un aspect de la présente invention, le dispositif à semiconducteur comprend : un premier substrat semiconducteur, sur lequel est formé un circuit prédéterminé; un second substrat semiconducteur lié au premier substrat semiconducteur; et une électrode traversante qui connecte électriquement le premier substrat semiconducteur et le second substrat semiconducteur l'un à l'autre. L'électrode traversante est formée par ouverture d'un trou traversant par pénétration d'une structure de diode de protection formée sur le premier substrat semiconducteur, déposer un film d'isolation sur la paroi latérale du trou traversant, et appliquer un matériau d'électrode sur le côté interne du trou traversant sur lequel le film isolant est déposé. La présente invention peut être appliquée, par exemple, à des capteurs d'image CMOS.
