Latest Patents

Among Han's latest inventions is the "Method for Fabricating a Super Self-Aligned Bipolar Transistor." This innovative technique focuses on the manufacturing process of a super self-aligned heterojunction bipolar transistor, which enhances miniaturization and simplifies manufacturing steps. By employing a selective collector epitaxial growth process, the method eliminates the need for trenches for isolation between elements, instead using a mask to define the emitter region along with a second spacer. The base layer, integral to this invention, features a multi-layer structure comprising silicon, an undoped silicon-germanium (SiGe), and a p-type doped SiGe. This approach significantly reduces leakage current risks and the potential for emitter-base-collector short effects.

Another noteworthy patent from Han is the "Method for Fabricating a Lateral Collector Structure on a Buried Oxide." This invention presents a collector device designed for bipolar applications, featuring a lateral collector structure positioned on a buried oxide layer. This design ensures high breakdown voltage for enhanced power handling and high-speed performance while effectively isolating the horizontal collector from the substrate.
