This document describes techniques for authenticating an identity of a semiconductor component using a physical identifier. In some aspects, a physical identifier comprised of a region of features located indiscriminately within a surface of an encapsulated semiconductor component is fabricated. The physical identifier is then mapped. The map is then stored for use when authenticating the identity of the semiconductor component.

Physical identifiers for authenticating an identity of a semiconductor component

A method includes forming an integrated circuit device having device circuitry disposed in a device circuitry area on a substrate and a destroyable circuit formed in a destroyable circuitry area on the substrate; testing at least one operational aspect of the device circuitry using the destroyable circuit; and destroying the destroyable circuit subsequent to testing the at least one operational aspect of the device circuitry.

Test then destroy technique for security-focused semiconductor integrated circuits
