Abstract:
A semiconductor component comprising:a substrate;a first doped region in the substrate;an electrostatic-discharge protection device in the substrate comprising a second doped region in the substrate wherein a first portion of the second doped region contacts the first doped region at a first portion of the substrate;a first interconnect layer overlying the electrostatic-discharge protection device, wherein a ring-shaped portion of the first interconnect layer overlies and contacts a second portion of the second doped region;a second interconnect layer overlying the first interconnect layer and the electrostatic-discharge protection device, wherein a portion of the second interconnect layer overlies and contacts the first interconnect layer, overlies the electrostatic-discharge protection device, is devoid of overlying the ring-shaped portion of the first interconnect layer, and is devoid of overlying the first and second portions of the second doped region; anda third interconnect layer overlying the first and second interconnect layers and the electrostatic-discharge protection device, wherein a portion of the third interconnect layer overlies and contacts the second interconnect layer, overlies the electrostatic-discharge protection device, and overlies the portions of the first and second interconnect layers.
