Claim:
1. A Schottky barrier diode comprising: a first semiconductor layer; a LOCOS layer arranged in contact with the first semiconductor layer; a first electrode arranged in contact with the first semiconductor layer on an upper surface of a mesa structure and forming a Schottky junction on a contact surface between the first semiconductor layer and the first electrode; a second semiconductor layer electrically connected to the first semiconductor layer and having a higher carrier concentration than that of the first semiconductor layer; and a second electrode forming an ohmic contact with the second semiconductor layer, wherein the LOCOS layer is in contact with a side surface of the mesa structure and the contact surface on which the Schottky junction is formed, and wherein the contact surface on which the Schottky junction is formed and the side surface of the mesa structure layer are in contact.
