Abstract
The disclosure provides a method to authenticate an integrated circuit (IC) structure. The method may include forming a first authentication film (AF) material within the IC structure. A composition of the first AF material is different from an adjacent material within the IC structure. The method includes converting the first AF material into a void within the IC structure. Additionally, the method includes creating an authentication map of the IC structure to include a location of the void in the IC structure for authentication of the IC structure.
