Latest Patents
Kou-Chio Liu holds a patent titled "Method of forming a HVNMOS with an N+ buried layer combined with N well and a structure of the same." This invention involves a device that includes an N-buried layer in a substrate. A P-well is formed in an epitaxial layer on the buried layer, while N-wells surrounding the P-well are also created in the epitaxial layer. One of the N-well regions serves as a drain in the structure. A plurality of field oxide regions is formed on the N-well or P-well to define the active area of the device. A gate oxide is formed on the surface of the P-well, and the N-well serves as the drain. A gate is constructed on the gate oxide, and a drain contact is established in the N-well. The source region of the device is formed in the P-well adjacent to the drain. An isolation layer is deposited on the gate. The method includes forming an N-buried layer in a P substrate, followed by the formation of a P epitaxial layer on the surface of the P substrate. The N-well and P-well are formed in the epitaxial layer through ion implantation and thermal diffusion. A plurality of field oxide (FOX) regions are created to define the active area, and a gate structure is patterned on the N-well and P-well. A drain contact in the drain (N-well) and a source region in the P-well over the N-buried layer are formed using conventional methods. An isolation layer is patterned on the gate structure for isolation.
