    摘要: Surface preparation of a compound semiconductor surface, such as indium antimonide (InSb), with a triflating agent, such as triflic anhydride or a trifluoroacetylating agent, such as trifluoroacetic anhydride is described. In one embodiment, the triflating or trifluoroacetylating passivates the compound semiconductor surface by terminating the surface with triflate trifluoroacetate groups. In a further embodiment, a triflating agent or trifluoroacetylating agent is employed to first convert a thin native oxide present on a compound semiconductor surface to a soluble species. In another embodiment, the passivated compound semiconductor surface is activated in an ALD chamber by reacting the triflate or trifluoroacetate protecting groups with a protic source, such as water (H2O). Metalorganic precursors are then introduced in the ALD chamber to form a good quality interfacial layer, such as aluminum oxide (Al2O3), on the compound semiconductor surface.

    摘要: A method for depositing a copper seed layer onto a semiconductor substrate comprises applying a SCuD plating bath onto a surface of a substrate, rinsing the surface with an organic solvent, applying a co-reactant bath to the surface, and again rinsing the surface with an organic solvent. The SCuD plating bath is non-aqueous and comprises a copper precursor that is dissolved into an organic solvent. The co-reactant bath is also non-aqueous and comprises a co-reactant dissolved into an organic solvent. The SCuD plating bath may be heated before being applied to the substrate surface.

    摘要: Self-aligned via patterning with multi-colored photobuckets for back end of line (BEOL) interconnects is described. In an example, an interconnect structure for an integrated circuit includes a first layer of the interconnect structure disposed above a substrate, the first layer including a first grating of alternating metal lines and dielectric lines in a first direction. The dielectric lines have an uppermost surface higher than an uppermost surface of the metal lines. A second layer of the interconnect structure is disposed above the first layer of the interconnect structure, the second layer including a second grating of alternating metal lines and dielectric lines in a second direction, perpendicular to the first direction. The dielectric lines have a lowermost surface lower than a lowermost surface of the metal lines of the second grating. The dielectric lines of the second grating overlap and contact, but are distinct from, the dielectric lines of the first grating. First and second dielectric regions are disposed between the metal lines of the first grating and the metal lines of the second grating, and in a same plane as upper portions of the dielectric lines of the first grating and lower portions of the dielectric lines of the second grating. The first dielectric region is composed of a first cross-linked photolyzable material, and the second dielectric region is composed of a second, different, cross-linked photolyzable material.
