An electrostatic discharge protection apparatus. A drain region is formed under a pad. A gate is formed at a periphery of the pad, while a source region is formed at a periphery of the gate. Another kind of electrostatic discharge protection apparatus is also presented with a drain region formed under a pad. More than one gate is formed at a periphery of the pad, and each gate is surrounded with a source region. Further in the invention, an electrostatic discharge protection apparatus is further presented with a P-type and N-type drain region located under a pad. A first gate and a second gate are formed at a periphery of pad corresponding thereto, respectively. In the above manners, the layout of the electrostatic discharge protection can be highly packed, that is, the occupied area is greatly reduced.
