    摘要: A clamping circuit is provided, which may clamp a voltage at a node of a circuit to a stable level by using a transistor already included in the circuit. The clamping circuit may clamp a voltage at a first node of a circuit inside a semiconductor chip to a more stable level when electro-static discharge (ESD) occurs. The clamping circuit may include a transistor and a capacitive element to store a control voltage to turn on the transistor in response to ESD.

    摘要: In an ESD protection device, a first well of a first conductivity type and a second well of a second conductivity type are formed in a substrate to contact each other. 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.

    摘要: 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.
