摘要: Disclosed is a silicon photoelectric multiplier having cell structure, which includes first type substrate; plurality of cells including epitaxial layer formed on the substrate, high concentration conductive layer, and second doped with opposite layer; trench to optically separate cells; guard ring an outer wall so as reach bottom surface thus further increasing degree optical separation thereby increase light detection efficiency.
