Abstract: PURPOSE:To improve the responding speed and the spike-resisting property of the titled semiconductor device as well as to let a diode to refrain from functioning as a transistor by a method wherein, in the semiconductor device on which a protective diode and a transistor are formed on a chip, the diffusion regions to be used for formation of a Schottky barrier diode, a Zener diode and a diode are constituted in a specific combination and arrangement. CONSTITUTION:As a Schottky barrier diode, formed with one conductivity type diffusion region 5 located on a semiconductor substrate 4 and the Schottky junction electrode 6 in the diffusion region 5, has a very short inverse recovery time, its responding speed is very high. Also, if the voltage of the Zener diode, which will be formed with the opposite conductivity type and one conductivity type double diffusion regions 7 and 8 to be formed on the circumference of the electrode 6, and an ohmic electrode 10, is properly controlled, the Schottky barrier diode which has a low resistivity for backward surge can be protected, and a highly spike-resisting protective movement of the transistor, formed with the diode and the electrode 6, can be prevented by the region 5 which is formed deeper than the base diffusion region 11 of the transistor. The assembling manhours of the semiconductor device can be reduced by forming the diode suitable for the characteristics of the transistor into one chip together with the transistor.
