  • Publication number: 20210399116
    Abstract: A structure includes a first source/drain region and a second source/drain region in a semiconductor body; and a trench isolation between the first and second source/drain regions in the semiconductor body. A first doping region is about the first source/drain region, a second doping region about the second source/drain region, and the trench isolation is within the second doping region. A third doping region is adjacent to the first doping region and extend partially into the second doping region to create a charge trap section. A gate conductor of a gate structure is over the trench isolation and the first, second, and third doping regions. The charge trap section creates a charge controlled e-fuse operable by applying a stress voltage to the gate conductor.
