  • Patent number: 7253480
    Abstract: A structure of an electrostatic discharge protection circuit, in which a buried layer is formed in the substrate of the electrostatic discharge protection circuit, and a sinker layer electrically connected to the buried layer and a drain is also formed therein. Thereby, when the electrostatic discharge protection circuit is activated, the current flows from a source through the buried layer and the sinker layer to the drain. The current flow path is remote from the gate dielectric layer to avoid damaging the gate dielectric by a large current, so as to improve the dielectric strength of the electrostatic discharge protection circuit.

  • Patent number: 7167072
    Abstract: An inductor formed on a substrate having a dielectric layer thereon is disclosed. The inductor includes a first inductor pattern, a second inductor pattern a third inductor pattern. The first inductor pattern is formed within the dielectric layer, the second inductor pattern is formed on the first inductor pattern and electrically connected thereto, and the third inductor pattern is formed on the second inductor pattern and electrically connected thereto, wherein the first inductor pattern, the second inductor pattern, and the third inductor pattern have similar pattern. Because the thickness of the inductor can be increased by forming a multi-layer inductor structure, the resistance of the inductor, therefore, is reduced.

  • Publication number: 20030197242
    Abstract: A structure of an electrostatic discharge protection circuit, using a deep trench structure to replace the guard ring at a periphery of the electrostatic discharge protection circuit. Consequently, the device area is smaller compared to the device with the guard ring. Moreover, the device area is further reduced because the distance between the transistors of the electrostatic discharge protection circuit is shortened. At the same time, the functions of latch-up immunity and substrate noise immunity are more effective.
