Abstract
1364035 Zener diodes ITT INDUSTRIES Inc 15 Feb 1973 [18 Feb 1972] 7431/73 Heading H1K A silicon Zener diode comprising a PN junction, the central area of which has a breakdown voltage less than 10 volts and lower than that of the surrounding portion of the junction, is made by diffusing donor impurity into one face of an N-type silicon wafer to produce a zone with a doping concentration between 10<SP>19</SP> atoms/c.c. and the degenerate concentration and then diffusing boron into the wafer to a plane of constant concentration within the donor diffused zone to form the central area of the junction. The wafer may have a resistivity of 10-100 milliohm/cm. due to antimony or phosphorus doping, and antimony contained in a silicon oxide layer is the preferred donor diffusant, though arsenic and phosphorus may be used if the source concentration is suitably controlled. In the preferred embodiment after donor diffusion into the entire surface an oxide mask with an annular aperture is formed on the zone and an acceptor diffused through it to provide a P ring 4 extending through the N+ zone 2. Then the boron is diffused through a mask having an aperture within the outer periphery of the annular aperture to form P + zone 3. In an alternative embodiment the N+ zone is formed by diffusion through a mask. The aperture in this mask is then enlarged and the boron diffused through it.
