  • Publication number: 20230116390
    Abstract: The embodiments herein describe authenticating a photomask used to fabricate an IC or a wafer. Because the IC may have been fabricated at a third-party IC manufacturer, the customer may want to ensure the manufacturer did not mistakenly use an incorrect mask, or that the mask was not altered or replaced with a rogue mask by a nefarious actor. That is, the embodiments herein can be used to identify when an IC manufacture (whether trusted or not) mistakenly used the wrong photomask, or to verify that a third-party IC manufacturer did not tamper with or replace the authentic photomask with a rogue mask. Advantageously, the embodiments herein can create a secure IC fabrication process to catch mistakes as well as ensure that non-trusted third-parties did not introduce defects into the IC.
