  • Method of manufacturing photo-diodes utilizing sequential diffusion
    Patent number: 4046609
    Abstract: A method of manufacturing a diode comprising a semiconductor body including at least first and second adjoining regions of the same conductivity type. The first region includes the diode junction and has a high resistivity, while the second region has a high impurity concentration that varies gradually and increases with increasing distance from the interface between the first and the second regions. The second region comprises two adjoining zones, the zone removed from the first region being more highly doped than the zone proximate said region. The second region is obtained by performing two successive diffusions of the same conductivity type as the first region to produce the two zones in said second region.
