Abstract: PURPOSE: A structure of a pin diode and a method of manufacturing the same are to minimize the forward resistance by enhancing a surface area of an Ohmic metal layer to be formed on an upper portion of a n-typed layer of high density. CONSTITUTION: A pin diode comprises a semiconductor substrate(11) having a protrusion, a n-typed layer(12) formed on the protrusion of the substrate, a buffer layer(13), a p-typed layer(14), a n-typed layer(14) formed on a slanted surface of the protrusion and the substrate, Ohmic metal layers each formed the p-typed layer and the n-typed layer, air-bridge metal layers each contacted with a region of the Ohmic metal layer. The semiconductor substrate is made of a compound of Ga and As. The n-typed layer and p-typed layer are formed by an epitaxial growing layer.
