  • Patent number: 11054459
    Abstract: A per-chip equivalent oxide thickness (EOT) circuit sensor resides in an integrated circuit. The per-chip EOT circuit sensor determines electrical characteristics of the integrated circuit. The measured electrical characteristics include leakage current. The determined electrical characteristics are used to determine physical attributes of the integrated circuit. The physical attributes, including EOT, are used in a reliability model to predict per-chip failure rate.

  • Publication number: 20180138209
    Abstract: An SOI substrate includes a metallic doped isolation (i.e., buried oxide) layer. Doping of the isolation layer increases its thermal conductivity, which improves heat conduction and decreases the susceptibility of devices formed on the substrate to temperature-induced deterioration and/or failure over time. The amount as well as the configuration of the doping can be tailored to specific circuit architectures.
