Abstract: Methods of forming structures including a photoresist absorber layer and structures including the absorber layer underlying an extreme ultraviolet (EUV) photoresist are disclosed. Exemplary methods include forming the photoresist absorber layer or underlayer with an oxide of a high atomic number (z) element having an EUV cross section (σα) of greater than 2×106 cm2/mol and then forming the EUV photoresist over the high-z underlayer.

Abstract: The disclosure relates to methods of selectively depositing material comprising a group 3 to 6 transition metal on a first surface of a substrate relative to a second surface of the substrate by a cyclic deposition process. The method includes providing a substrate in a reaction chamber, providing a transition metal precursor into the reaction chamber in a vapor phase, wherein the transition metal precursor comprises an aromatic ligand and providing a second precursor into the reaction chamber in a vapor phase to deposit transition metal on the first surface of the substrate. The disclosure further relates to a transition metal layers, and to deposition assemblies.

Abstract: Methods of forming structures including a photoresist absorber layer and structures including the photoresist absorber layer are disclosed. Exemplary methods include forming the photoresist absorber layer that includes at least two elements having an EUV cross section (σα) of greater than 2×106 cm2/mol.

Abstract: Methods of forming structures including a photoresist absorber layer and structures including the photoresist absorber layer are disclosed. Exemplary methods include forming the photoresist absorber layer that includes an element having a relatively high extreme ultraviolet (EUV) sensitivity on a mass basis while having a relatively low EUV sensitivity on a mole basis.
