Latest Patents

One of his latest patents is a method for fabricating an integrated circuit device with two gate structures. This innovative design includes a semiconductor substrate, a first gate structure, a channel layer, source and drain features, and a second gate structure. The first gate structure is positioned over the semiconductor substrate and comprises a gate dielectric layer and a first gate electrode. The channel layer is situated above and surrounded by the first gate structure, while the source and drain features are located on opposite sides of the channel layer. The second gate structure, which is positioned over the channel layer, includes a programming gate dielectric layer with a data storage layer and a second gate electrode. The first and second contacts are connected to the respective gate electrodes.

Another notable patent is related to self-aligned unsymmetrical gate (SAUG) FinFET structures and methods of forming them. The SAUG FinFET features two different gate structures on opposite sides of each fin: a programming gate structure and a switching gate structure. This technology can be utilized as a non-volatile memory storage element, which can be electrically programmed by trapping charges in the charge trapping dielectric. The stored data can be sensed by measuring the channel current through the SAUG FinFET in response to a bias on the switching gate.
