    摘要: The invention relates to a Zener diode with a semiconductor substrate (1), which comprises a n-type region (2) and a p-type region (3), whereby the doped regions (2, 3) form a lateral p-n junction (4) and the sides of said doped regions (2, 3), facing to each other, have a width (b) which decreases towards the other doped region (2, 3). Said invention also relates to a method for the production of said Zener diode as well as a Zener diode circuit. The flattened ends of the doped regions as well as the choice of a symmetrical arrangement permit alignment errors of the masks to be compensated for.

    摘要: There is a problem that a reverse off-leak current becomes too large in a Schottky barrier diode. A semiconductor device of the present invention includes P-type first and second anode diffusion layers 5, 6 formed in an N-type epitaxial layer 3, N-type cathode diffusion layers 4 formed in the epitaxial layer 3, a P-type third anode diffusion layer 7, 8 formed in the epitaxial layer 3 so as to surround the first and second anode diffusion layers 5, 6 and to extend toward the cathode diffusion layers 4, and a Schottky barrier metal layer 14 formed on the first and second anode diffusion layers 5, 6.

    摘要: A punch-through diode transient suppression device has a base region of varying doping concentration to improve leakage and clamping characterisics. The punch-through diode includes a first region comprising an n+ region (12), a second region comprising a p- region abutting the first region, a third region comprising a p+ region (16) abutting the second region, and a fourth region comprising an n+ region (18) abutting the third region. The peak dopant concentration of the n+ layers should be about 1.5E18 cm , the peak dopant concentration of the p+ layer should be between about 1 to about 5 times the peak concentration of the n+ layer, and the dopant concentration of the p- layer should be between about 0.5E14 cm and about 1.0E17 cm . The junction depth of the fourth (n+) region (18) should be greater than about 0.3 um. The thickness of the third (p+) region (16) should be between about 0.3 um and about 2.0 um, and the thickness of the second (p-) region should be between about 0.5 um and about 5.0 um.
