    摘要: A microelectronic device includes a metal gate with a metal gate upper surface. The metal gate is disposed in an interlayer dielectric first layer. The interlayer dielectric first layer also has an upper surface that is coplanar with the metal gate upper surface. A dielectric etch stop layer is disposed on the metal gate upper surface but not on the interlayer dielectric first layer upper surface.

    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 selective spacer for semiconductor and MEMS devices and method of manufacturing the same. In an embodiment, a selective spacer is formed adjacent to a first non-planar body having a greater sidewall height than a second non-planar semiconductor body in a self-aligned manner requiring no patterned etch operations. In a particular embodiment, a margin layer of a particular thickness is utilized to augment an existing structure and provide sufficient margin to protect a sidewall with a spacer that is first anisotropically defined and then isotropically defined. In another embodiment, the selective spacer formation prevents etch damage by terminating the anisotropic etch before a semiconductor surface is exposed.
