摘要:
In a semiconductor IC, a vertical pnp or npn transistor of a uniform characteristic and a high breakdown voltage is made by forming, for example, a p-collector region (39) in an n-type epitaxial region, an n-well base region (41) formed in the p -collector region (39) and a p-emitter region (42) formed in the n-well base region (41); and furthermore, for example as shown in Figure 9, p-regions (40) and (49) are formed simultaneously with the p-collector region (39) and an n-region (53) is formed simultaneously with the n-well base region (41), thereby constituting III of superior characteristics and a high resistance device at the same time as forming of the vertical transistor without substantial increase of manufacturing steps; and in the similar way, by combining the p-region and n-region formed in the above-mentioned simultaneous steps with other region formed simultaneously with the forming of the vertical transistor, high h FE transistor, high speed vertical npn transistor, cross-over devices, p-channel and/or n-channel MOS transistors can be formed within limited manufacturing steps.

The semiconductor device includes an 1 2 L device and a resistor element. A p-type buried layer 11 is formed on an n + -type substrate 10. An n-type epitaxial layer 12, 12', is grown on p-type layer 11. A ring shaped p + type region 13 is formed around part of the epitaxial layer 12', through the epitaxial layer 12' to the p-type layer 11. A resistor layer of n-type is provided in the epitaxial layer 12' surrounded by p + -type region 13. n + -type electrode connections 15 for the resistor are formed in the epitaxial layer 12' surrounded by the p + -type region 13.
摘要:
L'invention se rapporte au domaine des transistors bipolaires pour fonctionnement aux tensions élevées, supérieures à 100 V. La fabrication simultanée de ces transistors des différents types connus, à savoir pnp, pnp latéraux, non et 12L, en vue de les réunir par intégration monolithique sur un même substrat, rencontre de grandes difficultés par suite des incompatibilités entre certaines étapes de fabrication communes. Selon l'invention, il est créé, pour les surmonter dans les pnp et pnp latéraux, deux régions supplémentaires à taux de dopage élevé de signe n, l'une à la jonction d'émetteur (32), et l'autre à la jonction de collecteur (25). Les applications sont notamment relatives aux circuits intégrés pour tensions élevées à haut degré d'intégration.
摘要:
Die Erfindung betrifft einen integrierten bipolaren Halbleiterschaltkreis mit Transistoren großer Durchbruchspannung sowie Transistoren großer Aufwärtsstromverstärkung. Um bei einem solchen Halbleiterschaltkreis Durchbruchspannung und Aufwärtsstromverstärkung mit an die Schaltungsbedürfnisse anpaßbaren Größen unabhängig einstellen zu können, sieht die Erfindung vor, daß die Basiszonen (8, 8') der Transistoren großer Aufwärtsstromverstärkung im Vergleich zu den Basiszonen (4) der Transistoren großer Durchbruchspannung schwächer dotiert sind und in Richtung der Zonenfolge Emitter-Basis-Kollektor eine größere Tiefe (d 2 ) besitzen und daß die genannten Basiszonen (8, 8' bzw. 4) unabhängig voneinander hergestellt werden.
