人工物メトリクスのための量産型マイクロディスクの発振多様性に関する検証

抄録

To secure massive supply chain of semiconductor industry, accurate tracking and strict authentication of components are essential. To trace and identify each component, nano-artifact metrics technologies have been studied. We utilize inkjet technology to add microdisks as physical identifiers. Based on whispering gallery mode resonation, each microdisk reveals a unique lasing spectrum, expected to show lower false rejection and acceptance rates. This study confirms that mass-produced microdisks provide sufficient identities to be defined as a physically unclonable function of each component.
