Abstract:
(EN) A semiconductor substrate (1) has a front surface, and a rear surface on the reverse side of the front surface. Gate wiring (2) and first and second front surface electrodes (3, 4) are formed on the front surface of the semiconductor substrate (1). The first and second front surface electrodes (3, 4) are separated from each other by means of the gate wiring (2). An insulating film (7) is covering the gate wiring (2). Over the gate wiring (2), an electrode layer (8) is formed on the insulating film (7) and the first and second front surface electrodes (3, 4). A rear surface electrode (9) is formed on the rear surface of the semiconductor substrate (1). A first plated electrode (10) is formed on the electrode layer (8). A second plated electrode (11) is formed on the rear surface electrode (9).
(FR) Un substrat semi-conducteur (1) a une surface avant, et une surface arrière sur le côté arrière de la surface avant. Un câblage de grille (2) et des première et seconde électrodes de surface avant (3, 4) sont formés sur la surface avant du substrat semi-conducteur (1). Les première et seconde électrodes de surface avant (3, 4) sont séparées l'une de l'autre au moyen du câblage de grille (2). Un film isolant (7) recouvre le câblage de grille (2). Sur le câblage de grille (2), une couche d'électrode (8) est formée sur le film isolant (7) et les première et seconde électrodes de surface avant (3, 4). Une électrode de surface arrière (9) est formée sur la surface arrière du substrat semi-conducteur (1). Une première électrode plaquée (10) est formée sur la couche d'électrode (8). Une seconde électrode plaquée (11) est formée sur l'électrode de surface arrière (9).
(JA) 半導体基板(1)は互いに対向する表面及び裏面を持つ。ゲート配線(2)及び第1及び第2の表面電極(3,4)が半導体基板(1)の表面に形成されている。第1及び第2の表面電極(3,4)はゲート配線(2)により互いに分割されている。絶縁膜(7)がゲート配線(2)を覆っている。電極層(8)がゲート配線(2)を跨いで絶縁膜(7)及び第1及び第2の表面電極(3,4)の上に形成されている。裏面電極(9)が半導体基板(1)の裏面に形成されている。第1のめっき電極(10)が電極層(8)の上に形成されている。第2のめっき電極(11)が裏面電極(9)の上に形成されている。
