Latest Patents

Yi Ming Sheu holds a patent for an "Electrostatic discharge device protection structure." This invention effectively overcomes the problem of gate oxide damage by incorporating a region with very high defect density within the drain of the ESD protection device. The design ensures that no action occurs under low applied voltages. However, when high voltage is applied, the depletion layer expands enough to contact this high defect density region, allowing substantial current flow into the substrate. This mechanism results in lowering the voltage to a safe level. The high defect density region is created through ion implantation of heavy ions, such as germanium, after the completion of the normal manufacturing process.
