    摘要: A secure electronic structure including a plurality of sub-lithographic conductor features having non-repeating random shapes as a physical unclonable function (PUF) and an integrated circuit including the same are provided. Some of the conductor features of the plurality of conductor features form ohmic electrical contact to a fraction of regularly spaced array of conductors that are located above or beneath the plurality of conductor features having the non-repeating shapes, while other conductor features of the plurality of conductor features do not form ohmic electrical contact with any of the regularly spaced array of conductors. Thus, a unique signature of electrical continuity is provided which can be used as a PUF within an integrated circuit.

    摘要: A coating process comprises forming a patterned material layer on a substrate using a self-segregating polymeric composition comprising a polymeric photoresistive material and an antireflective coating material contained in a single solution. When depositing this solution on a substrate and removing the solvent, the two materials self-segregate into two layers. This produces a coated substrate having a uniaxial bilayer coating oriented in a direction orthogonal to the substrate with a top photoresistive coating layer and a bottom antireflective coating layer. Pattern-wise exposing the coated substrate to imaging radiation and contacting the coated substrate with a developer, produces the patterned material layer. Any optional top coat material and a portion of the photoresist layer can be simultaneously removed from the coated substrate to form a patterned photoresist layer on the substrate.
