  • Publication number: 20250098194
    Abstract: Continuous polysilicon on oxide diffusion edge (CPODE) processes are described herein in which one or more semiconductor device parameters are tuned to reduce the likelihood of etching of source/drain regions on opposing sides of CPODE structures formed in a semiconductor device, to reduce the likelihood of depth loading in the semiconductor device, and/or to reduce the likelihood of gate deformation in the semiconductor device, among other examples. Thus, the CPODE processes described herein may reduce the likelihood of epitaxial damage to the source/drain regions, may reduce current leakage between the source/drain regions, and/or may reduce the likelihood of threshold voltage shifting for transistors of the semiconductor device. The reduced likelihood of threshold voltage shifting may provide more uniform and/or faster switching speeds for the transistors, more uniform and/or lower power consumption for the transistors, and/or increased device performance for the transistors, among other examples.
