  • Patent number: 9202790
    Abstract: A semiconductor device for electrostatic discharge protection includes a substrate, a first well and a second well formed in the substrate. The first and second wells are formed side by side, meeting at an interface, and have a first conductivity type and a second conductivity type, respectively. A first heavily doped region and a second heavily-doped region are formed in the first well. A third heavily doped region and a fourth heavily-doped region are formed in the second well. The first, second, third, and fourth heavily-doped regions have the first, second, second, and first conductivity types, respectively. Positions of the first and second heavily-doped regions are staggered along a direction parallel to the interface.

  • Patent number: 9136229
    Abstract: An electrostatic discharge (ESD) protection device is provided. A proper trigger voltage is determined by providing an ESD doped injection layer into a PNPN structure and adjusting the injection energy and dosage of the ESD doped injection layer; a proper holding voltage is obtained by adjusting the size of the ESD doped injection layer, thus preventing the latch-up. The self-isolation effect of the electrostatic discharge protection device is formed on the basis of an epitaxial wafer high voltage process or a silicon-on-insulator (SOI) wafer high voltage process, the ESD protective device of the present invention can prevent the device from being falsely triggered due to noise interference. Compared with other known ESD protection devices, the device has the same electrostatic protection ability, much smaller area, and much lower cost.
