  • Publication number: 20120320477
    Abstract: An integrated circuit chip including a plurality of parallel wells of alternated conductivity types formed in the upper portion of a semiconductor substrate of a first conductivity type, and a device of protection against attacks including: between the wells, trenches with insulated walls filled with a conductive material, said trenches extending from the upper surface of the wells to the substrate; and a circuit capable of detecting a modification of the stray capacitance formed between said conductive material and a region of the chip.
    Type: Application

  • Publication number: 20120320480
    Abstract: An integrated circuit chip includes: a plurality of parallel wells of alternated conductivity types formed in the upper portion of a semiconductor substrate of a first conductivity type; in each well of the first type, a plurality of MOS transistors having a channel of the second conductivity type, and in each well of the second type, a plurality of MOS transistors having a channel of the first type, transistors of neighboring wells being inverted-connected; and a device of protection against attacks, including: a layer of the second type extending under said plurality of wells, from the lower surface of said wells; and regions of lateral insulation between the wells, said regions extending from the upper surface of the wells to said layer.
