Latest Patents
One of Lien's latest patents is titled "ESD protection devices and methods for reducing trigger voltage." This invention provides ESD protection devices that utilize a thin gate oxide fabricated through a dual gate oxide process. The result is a lower trigger voltage for ESD protection devices. The NMOS for ESD protection features islands with thin gate oxides and a control gate with a thick gate oxide. These islands overlap the drain region of the NMOS, which helps reduce the breakdown voltage of the PN junction in the drain region. Consequently, this innovation lowers the ESD trigger voltage and enhances the ESD protection level of the NMOS. Furthermore, this invention is applicable to general integrated-circuit processes and various ESD protection devices.
Another significant patent by Lien is the "Electrostatic discharge protection circuit." This device includes a semiconductor layer with a source region, a drain region, and a channel region situated between the source and drain regions. A gate is positioned over the channel region. The design incorporates a plurality of current divider segments distributed on the drain region, extending between the gate and drain contacts. These segments can be constructed from polysilicon or a field oxide, further improving the device's functionality.
