  • Publication number: 20240065082
    Abstract: A semiconductor device that facilitates absorption of EM radiation thereon and a method manufacturing same. The device extends in at least one lateral aspect. An EM radiation-absorbing layer comprising a discontinuous layer of at least one particle structure comprising a deposited material is deposited on a first layer surface. The particle structures facilitate absorption of EM radiation incident thereon and may comprise a seed about which the deposited material may tend to coalesce, and/or comprise the deposited material co-deposited with a co-deposited dielectric material. The EM radiation-absorbing layer may be disposed on a supporting dielectric layer and/or be covered by a covering dielectric layer. A patterning coating having an initial sticking probability against deposition of the deposited and/or a seed material, on a surface of the patterning coating is less than the initial sticking probability against deposition of the deposited and/or seed material on the second layer surface.
