The semiconductor chip includes a substrate. The semiconductor chip includes multiple devices formed on the substrate. Each device includes multiple fins. A gate is formed on the multiple fins with a gate cut (CT) design that results in random distribution of complete gate cut and incomplete gate cut for each of the multiple devices based on a natural process variation in semiconductor manufacturing for each device. A physical unclonable function (PUF) region is defined in accordance with the random distribution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sublithography gate cut physical unclonable function","description":"Methods, and devices related to authentication of chips using physical unclonable function (PUF) are disclosed.
