IPC: H01L21/331
Filed: 1993-08-04
Abstract: PURPOSE:To stabilize a Zener voltage by making an oxide film on an N<+> type diffusion layer thicker as the impurity concentration of the N<+> type diffusion layer becomes low, in accordance with the relation between the breakdown voltage of a transistor and the impurity concentration of the N<+> type diffusion layer. CONSTITUTION:A P-type diffusion layer 3 functions as the base of a transistor, and base electrode layer 7 is connected with the P-type diffusion layer 3, via an aperture formed in an oxide film 6. The base electrode layer 7 is led out on the oxide film 6, and extended over the N<-> type silicon substrate 1 as far as a part above the N<+> type diffusion layer 5. The thickness (t) of the oxide film 6 between the N<+> type diffusion layer 5 and the base electrode layer 7 is made thicker as the impurity concentration of the N<+> type diffusion layer 5 becomes low, in accordance with the relation between the breakdown voltage of a transistor and the impurity concentration of the N<+> type difusion layer 5. Thereby the Zener voltage is stabilized, and a high breakdown voltage necessary for a transistor can be realized.
