The device includes an integrated circuit having a semiconducting material in at least one via in a backend of the integrated circuit. The present disclosure also relates to a method for manufacturing a secure device having a physical unclonable function. The method includes providing an integrated circuit and adding a semiconducting material to at least one via in a backend of the integrated circuit. In some instances a property of the semiconducting material in the at least one via is measured to derive a signature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reliable physical unclonable function for device authentication","description":"The present disclosure relates to a secure device having a physical unclonable function.
