摘要:
A microcomputer is equipped with a CPU and an AD converter. The AD converter is supplied with the same power source voltage as the CPU, and converts a reference voltage into digital data using the received power source voltage and outputs the digital data as a conversion value. The CPU detects a state of the power source voltage by calculating a voltage variation of a power source voltage for ordinary operation on the basis of a first conversion value obtained by AD-converting the reference voltage by the AD converter in a state that a standard power source voltage including no voltage variation is supplied to the AD converter and a second conversion value obtained by AD-converting the reference voltage by the AD converter in a state that the power source voltage for ordinary operation is supplied to the AD converter.

A microcomputer 10 is equipped with a CPU 13 and an AD converter 15. The AD converter 15 is supplied with the same power source voltage as the CPU 13, and converts a reference voltage Vref into digital data using the received power source voltage and outputs the digital data as a conversion value. The CPU 13 detects a state of the power source voltage by calculating a voltage variation of a power source voltage for ordinary operation on the basis of a first conversion value obtained by AD-converting the reference voltage Vref by the AD converter 15 in a state that a standard power source voltage Vcc including no voltage variation is supplied to the AD converter 15 and a second conversion value obtained by AD-converting the reference voltage Vref by the AD converter 15 in a state that the power source voltage for ordinary operation is supplied to the AD converter 15.

In a microcomputer 10 which converts an analog signal Vin into digital data and corrects an error of the digital data, a voltage variation ΔVcc is calculated on the basis of a first conversion value obtained by AD-converting a reference voltage Vref by an AD converter 15 in a state that a standard power source voltage including no voltage variation is supplied to the AD converter 15 and a second conversion value obtained by AD-converting the reference voltage Vref by the AD converting section in a state that a power source voltage for the ordinary operation is supplied to the AD converter 15. The digital data produced by the AD converter 15 by AD-converting the analog signal Vin is corrected using the calculated voltage variation ΔVcc.

In order that a top surface of a gate electrode does not have sharp portions, ends of the top surface of the gate electrode are rounded before refractory metal is deposited for silicidation. This reduces intensive application of film stresses which are generated in heat treatment, enabling formation of a silicide layer with a uniform, sufficient thickness.
