    • A schottky barrier diode having improved electrical property is provided to improve a current leakage property by forming an contrary impurity region like a P-type impurity region to an anode region, and to improve forward current performance by forming an N-well in a cathode region. A first N-well is formed on a P-type substrate. A cathode includes a second N-well which is formed on the first N-well, and an N-type impurity region which is formed on the second N-well. An anode includes a P-type impurity region formed on the first N-well, and is separated from the cathode and surrounded by that. An N-type metal region is further included between the second N-well and the N-type impurity region.

    • A method for manufacturing a semiconductor device is provided to simplify manufacturing processes by performing simultaneously a heat treatment on a zener region, a first active region and a second active region. A second conductive type well region(201) is formed in a first conductive type semiconductor substrate. A first conductive type zener region(203) is formed in the resultant structure. A gate electrode(206) is formed on the substrate without annealing. A first active region(207) is formed at one side of the gate electrode. A second active region(208) is formed at the other side of the gate electrode. Then, an annealing process is performed on the resultant structure.
