Latest Patent Applications
Chen-Dong Tzou has filed several patent applications, including one titled "SEMICONDUCTOR DEVICE AND METHODS FOR FORMING THE SAME." This application describes a semiconductor device that includes a substrate of the first conductivity type, an epitaxial layer of the first conductivity type, doping portions of the second conductivity type, a trench structure, a well region of the second conductivity type, and a gate structure on the epitaxial layer and over the well region. The epitaxial layer consists of a first epitaxial portion on the substrate and a second epitaxial portion on the first epitaxial portion. The doping portions are formed in the first epitaxial portion, while the trench structure is formed in the second epitaxial portion, extending from the top surface and contacting one of the doping portions. The well region's first sidewall is in contact with the trench structure, while the second sidewall and the bottom surface are in contact with the second epitaxial portion.
Another application under his name also titled "SEMICONDUCTOR DEVICE AND METHODS FOR FORMING THE SAME" details a semiconductor device that includes a substrate with a first conductivity type and an epitaxial layer on the substrate. This device comprises a first device with a trench gate structure and a shielding portion, where the substrate functions as the drain. The second device, electrically connected to the first, includes a second trench gate structure, a planar gate structure, and a second shielding portion. Both trench gate structures extend downward from the top surface of the epitaxial layer into it, with the shielding portions in contact with the bottoms of the respective trench gate structures.
Conclusion
Chen-Dong Tzou is an innovative inventor in the semiconductor field, contributing valuable ideas through his latest patent applications. His work reflects a commitment to advancing technology in this critical area.
