    摘要: A semiconductor device has lateral conductors or traces that are formed of nanotubes such as carbon. A sacrificial layer is formed overlying the substrate. A dielectric layer is formed overlying the sacrificial layer. A lateral opening is formed by removing a portion of the dielectric layer and the sacrificial layer which is located between two columns of metallic catalysts. The lateral opening includes a neck portion and a cavity portion which is used as a constrained space to grow a nanotube. A plasma is used to apply electric charge that forms an electric field which controls the direction of formation of the nanotubes. Nanotubes from each column of metallic catalyst are laterally grown and either abut or merge into one nanotube. Contact to the nanotube may be made from either the neck portion or the columns of metallic catalysts.

    摘要: A metal layer etch process deposits, patterns and anisotropically etches a polysilicon layer (24) down to an underlying metal layer (22) to form an etched polysilicon structure (54) with polymer layers (50, 52) formed on its sidewall surfaces. The polymer layer (50, 52) are removed to expose an additional surface area (60, 62) of the metal layer (22), and dielectric layers (80, 82) are formed on the sidewall surfaces of the etched polysilicon structure (54). Next, the metal layer (22) is plasma etched to form an etched metal layer (95) with substantially vertical sidewall surfaces (97, 99) by simultaneously charging the dielectric layers (80, 82) to change plasma ion trajectories near the dielectric layers (80, 82) so that plasma ions (92, 94) impact the sidewall surfaces (97, 99) in a more perpendicular angle to enhance etching of the sidewall surfaces (97, 99) of the etched metal layer (95).

The plasma tuning rod subsystems can comprise one or more microwave cavities configured to couple electromagnetic (EM) energy in a desired EM wave mode to a plasma by generating resonant microwave energy in one or more plasma tuning rods within and/or adjacent to the plasma. One or more microwave cavity assemblies can be coupled to a process chamber, and can comprise one or more tuning spaces/cavities. Each tuning space/cavity can have one or more plasma tuning rods coupled thereto. Some of the plasma tuning rods can be configured to couple the EM energy from one or more of the resonant cavities to the process space within the process chamber and thereby create uniform plasma within the process space.
