Abstract
PURPOSE: To provide a semiconductor integrated circuit wherein two P type regions are diffusion-formed in an N type substrate, an N type region is provided in one of said regions, another P type region is connected to said region by an outside conductive line to generate an electrostatic capacity, thereby to reduce the tip area upon the integration.
CONSTITUTION: P type regions P2 and P3 are diffusion-formed in an N type semiconductor substrate N1, and further an N type region N2 is provided in the region P2 and an N type region N3 is provided in the substrate 1 between the regions P2 and P3. In this manner, a NPN transistor 1 is constituted by regions N1, P2 and N2, and the space between the region P3 and the substrate N1 is used as a diode. Thereafter, the regions P3 and N2 are connected to each other by an outside conductive wire, and a condenser is produced between these regions. According to this arrangement, an electrostatic capacity can be produced only by diffusion, and the manufacturing process becomes extremely easy.
