A first impurity region of the first conductivity type and a second impurity region of the second conductivity type are formed in the first well, and are electrically connected to a first electrode pad. The second impurity region is spaced apart from the first impurity region in a direction of the second well. A third impurity region is formed in the second well, has the second conductivity type, and is electrically connected to a second electrode pad. A fourth impurity region is formed in the second well, is located in a direction of the first well from the third impurity region to contact the third impurity region, has the first conductivity type, and is electrically floated.

The present invention disclosed herein is a Vertical Double-Diffused Metal Oxide Semiconductor (VDMOS) device incorporating a reverse diode. This device includes a plurality of source regions isolated from a drain region. A source region in close proximity to the drain region is a first diffusion structure in which a heavily doped diffusion layer of a second conductivity type is formed in a body region of a second conductivity type. Another source region is a second diffusion structure in which a heavily doped diffusion layer of a first conductivity type and a heavily doped diffusion layer of the second conductivity type are formed in the body region of the second conductivity type. An impurity diffusion structure of the source region in close proximity to the drain region is changed to be operated as a diode, thereby forming a strong current path to ESD (Electro-Static Discharge) or EOS (Electrical Over Stress). As a result, it is possible to prevent the device from being broken down.

A transistor with an electrical overstress (EOS) protection may include an active region, a plurality of impurity regions and a conduction pattern. The active region may be formed in a substrate. The impurity regions may be formed in the active region and arranged at a predetermined or given distance with respect to each other. The conduction pattern may be arranged between each of the impurity regions in a meandering shape, and the conduction pattern may include a center portion connected to a ground terminal. Therefore, a transistor with EOS protection, a clamp device, and an ESD protection circuit including the same may increase an on-time of a clamp device and may sufficiently discharge a charge due to the EOS by including a conduction pattern configured with gates that are connected with respect to each other in a meandering shape.
