Abstract: PURPOSE:To prevent a tunnel part and a silicon oxide film from being lowered in dielectric strength by forming a silicon oxide film over the tunnel part on the semiconductor substrate surface, and thereafter forming the silicon oxide film on a region other than the tunnel part. CONSTITUTION:A first silicon oxide film 18 of the same thickness as that of a tunnel part is formed on a semiconductor substrate 10, and an oxidation- resistant film 19 is formed on the surface of the silicon oxide film 18. For the first silicon oxide film 18 and the oxidation resistant film 19, a region corresponding to the tunnel part is left behind using photoetching and the other region is removed to expose the surface of the semiconductor substrate 10. A second silicon oxide film 7 with thickness greater than that of the tunnel part is formed on the exposed surface of the semiconductor substrate 10. Further, a polycrystalline silicon film 3 is formed on the surfaces of the oxidation- resistant film 19 and the second silicon oxide film 9. Hereby, there can be improved dielectric resistance of the silicon oxide film and tunnel oxide film located under a select gate.

Title: Amplifier circuit
Inventor: SEKIGUCHI SATOSHI
IPC: H03F3/45
Filed: 1986-09-26
Abstract: PURPOSE:To reduce the offset voltage of an amplifier by supplying the base current of a transistor(TR) which performs amplifying operation to a current mirror circuit which inputs a current corresponding to a current flowing in the TR. CONSTITUTION:The current mirror circuit 13 consists of two NPN TRs Q11 and Q12 and one PNP TR Q13. The base current Ib of the TR Q13 flows to the TR Q12 and the output current of the TR Q11, i.e. suction current it set to Ib. The base current Ib1 of a TR Q1 is sucked by the current mirror 13 and does not flow to an input resistance R0. Therefore, neither the Ib1 nor the R0 has a voltage drop and the bias voltages of the TRs Q1 and Q2 are stabilized with a reference voltage Vref. Thus, the variation in the bias voltages of the TRs due to the voltage drop across the input resistance is reduced.
