    摘要: A semiconductor rectifier includes a substrate of a first conductivity type; a current path layer of the first conductivity type formed near the surface of the substrate; a current block layer of a second conductivity type laterally enclosing the current path layer and extending to a depth deeper than the current path layer; and first and second metal layers formed respectively contacting upper and lower surfaces of the substrate. The current path layer has an impurity concentration higher than that of the substrate, and the current block layer has an impurity concentration higher than that of the current path layer. The current path layer is small enough for the portion below the current path layer to be completely blocked by the depletion region formed around the current block layer when a reverse bias or no is applied to the rectifier. The current path layer and the current block layer can be formed in an epitaxial layer of the first conductivity type overlying a high-concentration substrate of the first conductivity type, and a buried layer of the second conductivity type below the current block layer can further reduce reverse bias current.
