Abstract
PURPOSE: To form Zener diode and pinch resistance element into an integrated circuit under satisfactory correlation by beforehand making different the conductivity of an area constituting Zener diode and the conductivity of an area forming pinch resistance element.
CONSTITUTION: Zener diode D2 is composed of p-type area 5, p-type area 6 and n-type area 8. Zener voltage is determined by the forming conditions of pn-junction between p-type area 6 and n-type area 8. While pinch resistance element RP is constituted by a narrow long portion of p-type area 7 sandwiched between n-type area 2B and n-type area 10. Its resistance value is determined by the forming conditions of pn-junction between p-type area 7 and n-type area 10. As the forming conditions are the same, the Zener voltage of Zener diode DZ and the resistance value of pinch resistance element RP have close correlation with each other.
