Latest Patents

One of his latest patents is a method for fabricating a super self-aligned bipolar transistor. This invention relates to a manufacturing process that allows for miniaturization of elements while simplifying the steps involved. By employing a selective collector epitaxial growth process, it eliminates the need for a trench to isolate elements. The isolation is achieved using a mask that defines the emitter region and a second spacer. The base layer consists of a multi-layer structure made from silicon, undoped silicon-germanium, and p-type doped silicon-germanium. This method reduces the likelihood of leakage current and short effects between the emitter, base, and collector.

Another notable patent is the fabrication method of a T-shaped gate electrode in semiconductor devices. This method is particularly applicable to high-speed semiconductor devices, such as high electron mobility transistors (HEMTs), which are essential for high-speed logic circuits and low-noise receivers. The invention addresses the challenges of conventional photolithography techniques by utilizing a silicon oxide or silicon nitride film to form a dummy pattern. This allows for the creation of a gate electrode with a very fine line width without requiring additional steps to improve resolution.
