▎ 摘　　要

NOVELTY - Manufacture of physically unclonable function (PUF) security device involves preparing a silicon substrate, coating a solution containing a two-dimensional material on the silicon substrate, and heating the silicon substrate to evaporate the solvent of the solution. The two-dimensional material has an average length of 100-400 nm, and a thickness of 1-8 layers. USE - Manufacture of physically unclonable function (PUF) security device used for physically unclonable function security chip (all claimed) used for protecting numerous data, software-based security technology and hardware-based security technology. ADVANTAGE - The method enables to manufacture polyvinyl chloride security element in a simple and cost-effective manner with high-efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: the physically unclonable function security device; and physically unclonable function security chip.
