    摘要: A microwave plasma processing apparatus (100) of a slot antenna type includes a plane antenna plate (31) constituting a flat waveguide and a cover (34) of a conductive member. The cover (34) is provided with a stub (43) as a second waveguide for adjusting electric field-distribution in the flat waveguide. The stub (43) is provided in the cover (34) of the conductive member. In plan view, the stub (43) is arranged to overlap slots (32) constituting a slot pair arranged at the outermost circumference of the plane antenna plate (31). By appropriately arranging the stub, it is possible to control electric field-distribution in the flat waveguide thereby to generate a uniform plasma.

    摘要: A plasma processing apparatus includes a first electrode and a second electrode so arranged in the upper portion of a processing chamber as to face a mounting table, a gas supply unit for supplying a processing gas between the first electrode and the second electrode, a RF power supply unit for applying a RF power between the first electrode and the second electrode for converting the process gas supplied between the electrodes into a plasma, and a gas exhaust unit for evacuating the inside of the processing chamber to a vacuum level from the lower portion of the processing chamber. Since the electron temperature in the plasma is low near a substrate on the mounting table, damage to the substrate caused by the plasma can be suppressed. In addition, since a metal can be used as a material for the processing chamber, the processing chamber can have good temperature controllability.

    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 chromeless phase lithography mask (30) that does not require photoresist to manufacture has a quartz substrate (32) is etched by using a plasma (38) containing one of a nitrogen augmented hydro-fluorocarbon oxygen mixture and a nitrogen augmented fluorocarbon oxygen mixture. Various hydro-fluorocarbons or fluorocarbons may be used. The nitrogen addition results in etched openings in the quartz substrate that have substantially vertical sidewalls in a uniform manner across the substrate. Surface roughness is minimized and edges of the openings are well-defined with minimal rounding. The etch rate is rendered controllable by reducing bias power without degrading a desired vertical sidewall profile.

    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).

    摘要: A semiconductor manufacturing apparatus and process for forming a nitrided dielectric film includes generating a plasma source (44) over a wafer structure (46), where the plasma source (44) includes neutral species (such as nitrogen atoms) and charged species (such as nitrogen ions) that are formed in an inductively coupled plasma reactor. Before the charged species in the plasma (44) can penetrate the wafer structure (46), an electrically connected mesh structure (45, 47) between the plasma source (44) and wafer structure (46) blocks the charged species. In addition or in the alternative, a magnetic field (69) aligned in parallel with the surface of the wafer structure (66) is established in close proximity to the wafer structure (66) in order to trap the charged species. By removing charged species, an improved, narrower nitrogen concentration profile is obtained.
