Latest Patents

Yu-Hsuan Chang's latest patents include a diode structure and a manufacturing method thereof. This invention discloses a diode structure that comprises a semiconductor substrate, a first semiconductor layer, a second semiconductor layer, and an epitaxy layer. The semiconductor substrate features a first surface, with both semiconductor layers extending into the substrate by implanting a dopant. Notably, the types of the first and second semiconductor layers are opposite to that of the substrate. The epitaxy layer connects with both semiconductor layers and extends outwardly from the first surface, ensuring a continuous connection. The concentration distribution of the dopant within these layers follows a discontinuous curve.

Another significant patent is the transient-voltage-suppression diode structure and its manufacturing method. This structure includes a substrate, an N− type epitaxial layer, a first metal layer, a first N+ type implant layer, a deep N+ type implant layer, and multiple polycrystalline plugs. The N− type epitaxial layer is positioned on the substrate, while the first metal layer forms a working-voltage terminal. The first N+ type implant layer is embedded in the N− type epitaxial layer and corresponds spatially to the working-voltage terminal. The deep N+ type implant layer is also embedded in the N− type epitaxial layer but is spaced apart from the first N+ type implant layer. The polycrystalline plugs connect the working-voltage terminal to the deep N+ type implant layer.
