Latest Patents

Ellen Lan's latest patents include an innovative electrode structure for transistors and non-volatile memories. This electrode structure is designed for semiconductor devices and features a first electrode material positioned in an overlying relationship to the substrate surface. It defines a first side wall that is perpendicular to the substrate. A nonconductive side wall spacer is formed on this first side wall, creating a second side wall that is parallel and spaced from the first. Additionally, a second electrode material is formed in an overlying relationship to the substrate and on the second side wall, defining a third side wall that is also parallel and spaced from the second side wall. The first and second electrode materials are connected as first and second electrodes in a common semiconductor device. Furthermore, additional electrodes can be formed by applying electrode material on additional side walls.

Another notable patent involves a method of fabricating a vertical FET with a sidewall gate electrode. This process includes etching through a contact layer into a drift layer on a compound semiconductor substrate to create multiple mesas. Each mesa has an upper surface, and adjacent pairs of mesas define trenches with sidewalls and a bottom. A conductive layer is conformally deposited over the mesas and trenches, which is then anisotropically etched to form contacts on the sidewalls of the trenches. Source contacts are deposited on the upper surfaces of the mesas, while a drain contact is placed on the reverse side of the substrate.
