  • Technique for improving negative potential immunity of an integrated circuit
    Patent number: 7470955
    Abstract: An integrated circuit (IC) with negative potential protection includes at least one double-diffused metal-oxide semiconductor (DMOS) cell formed in a first-type epitaxial pocket, which is formed in a second-type substrate. The IC also includes a second-type+ isolation ring formed in the substrate to isolate the first-type epitaxial pocket and a first-type+ ring formed through the first-type epitaxial pocket between the second-type+ isolation ring and the DMOS cell.

  • Protection device for handling energy transients
    Patent number: 7279773
    Abstract: A protection device for handling energy transients includes a plurality of basic unit Zener diodes connected in series to achieve a desired breakdown voltage. Each of the basic unit Zener diodes is formed in a first-type substrate. Each of the basic unit Zener diodes comprises a second-type well formed in the substrate, a second-type Zener region formed in the second-type well and a first-type+ region formed over the second-type Zener region between a first and second second-type+ region.
