More Information
Summary:The utility model belongs to a photo-sensitive receiver for large view-field range in the technical field of semiconductors. The utility model solves the problem that the view field of a photo-sensitive device is small. The utility model adopts a cylinder-shaped or sphere-shaped semiconductor substrate (4). An impurity diffused layer (3) is formed on the substrate (4) to form the cylinder-shaped or sphere-shaped PN junction. An electrode (2) and an electrode (5) can be manufactured on both surfaces of the PN junction. The non-photo sensitive area can adopt a silicon dioxide layer (1) to protect the PN junction. The utility model can form the photo-sensitive receiver with a cylinder shape or a sphere shape, and can be used for large view-field measuring systems.
