摘要:
Disclosed are embodiments of a structure with a metal silicide transparent conductive electrode, which is commercially viable, robust and safe to use and, thus, optimal for incorporation into devices, such as flat panel displays, touch panels, solar cells, light emitting diodes (LEDs), organic optoelectronic devices, etc. Specifically, the structure can comprise a substrate (e.g., a glass or plastic substrate) and a transparent conducting film on that substrate. The transparent conducting film can comprise a metal silicide nanowire network. For example, in one embodiment, the metal silicide nanowire network can comprise multiple metal silicide nanowires fused together in a disorderly arrangement so that they form a mesh. In another embodiment, the metal silicide nanowire network can comprise multiple metal silicide nanowires patterned so that they form a grid. Also disclosed herein are various different method embodiments for forming such a structure.

摘要:
An underlying interconnect level containing underlying W vias embedded in a dielectric material layer are formed on a semiconductor substrate. A metallic layer stack comprising, from bottom to top, a low-oxygen-reactivity metal layer, a bottom transition metal layer, a bottom transition metal nitride layer, an aluminum-copper layer, an optional top transition metal layer, and a top transition metal nitride layer. The metallic layer stack is lithographically patterned to form at least one aluminum-based metal line, which constitutes a metal interconnect structure. The low-oxygen-reactivity metal layer enhances electromigration resistance of the at least one aluminum-based metal line since formation of compound between the bottom transition metal layer and the dielectric material layer is prevented by the low-oxygen-reactivity metal layer, which does not interact with the dielectric material layer.
摘要:
A structure which ensures against deterioration of an underlying silicide layer over which a refractory material layer is deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) is realized by first providing a continuous polysilicon layer prior to the refractory material deposition. The continuous polysilicon layer, preferably no thicker than 50 Å, serves a sacrificial purpose and prevents damage to an underlying silicide layer by blocking interaction between any fluorine and the underlying silicide that is released when the refractory material is formed.

摘要:
A semiconductor fabrication method comprises providing a structure which includes a semiconductor substrate having a plurality of subsurface layers, the substrate comprising a top surface and the subsurface layers comprising a top subsurface layer below the top surface of the substrate. A protective material is patterned on the top surface of the device and a material removal process is performed to simultaneously form a contact trench and an isolation trench, the material removal process removing at least a portion of the top surface and the top subsurface layer such that the contact trench and the isolation trench are formed within the subsurface layer. An insulator is then formed within the isolation trench and the contact trench is lined with the insulator. The contact trench is then filled with a conductive material such that the conductive material is deposited over the insulator.
