    摘要: A fabrication process for a MIM capacitor comprises providing a substrate, depositing a first metal layer on a dielectric layer of the substrate, forming an interfacial layer on the first metal layer, wherein the interfacial layer has a hydroxyl terminated surface, depositing a capacitor dielectric layer on the interfacial layer using an ALD process, and depositing a second metal layer on the capacitor dielectric layer. The interfacial layer may be formed by depositing a thin layer of a metal oxide, by oxidizing a surface of the first metal layer with an oxygen plasma, or by evaporating a thin metal oxide onto the surface of the first metal layer.

    摘要: Embodiments of the present invention describe a method of fabricating low resistance contact layers on a semiconductor device. The semiconductor device comprises a substrate having source and drain regions. The substrate is alternatingly exposed to a first precursor and a second precursor to selectively deposit an amorphous semiconductor layer onto each of the source and drain regions. A metal layer is then deposited over the amorphous semiconductor layer on each of the source and drain regions. An annealing process is then performed on the substrate to allow the metal layer to react with amorphous semiconductor layer to form a low resistance contact layer on each of the source and drain regions. The low resistance contact layer on each of the source and drain regions can be formed as either a silicide layer or germanide layer depending on the type of precursors used.
