    摘要: A method of processing a thin film structure on a semiconductor substrate using an optically writable mask, the method includes placing the substrate in a reactor chamber, the substrate having on its surface a target layer to be exposed to a light source in accordance with a predetermined pattern, depositing an optically writable carbon-containing mask layer on the substrate by (a) introducing a carbon-containing process gas into the chamber, (b) generating a reentrant toroidal RF plasma current in a reentrant path that includes a process zone overlying the workpiece by coupling plasma RF source power to an external portion of the reentrant path, (c) coupling RF plasma bias power or bias voltage to the workpiece. The method further includes optically writing on the carbon-containing mask layer in accordance with the predetermined pattern with writing light of a characteristic suitable for transforming the transparency or opacity of the optically writable mask layer and exposing through the mask layer the target layer with reading light of a characteristic different from that of the writing light.

    摘要: A method of forming a conductor in a thin film structure on a semiconductor substrate includes forming high aspect ratio openings in a base layer having vertical side walls, depositing a dielectric barrier layer comprising a dielectric compound of a barrier metal on the surfaces of the high aspect ratio openings including the vertical side walls, depositing a metal barrier layer comprising the barrier metal on the first barrier layer, depositing a main conductor species seed layer on the metal barrier layer and depositing a main conductor layer. The method further includes annealing the main conductor layer by (a) directing light from an array of continuous wave lasers into a line of light extending at least partially across the thin film structure, and (b) translating the line of light relative to the thin film structure in a direction transverse to the line of light. The method of Claim 1 further comprising, prior to the annealing step, depositing an amorphous carbon optical absorber layer on the main conductor layer. The step of depositing an amorphous carbon optical absorber layer includes introducing a carbon-containing process gas into a reactor chamber containing the substrate in a process zone of the reactor, applying RF source power to an external reentrant conduit of the reactor to generate a reentrant toroidal RF plasma current passing through the process zone and applying a bias voltage to the substrate.

    摘要: The time between illumination of adjacent zones of a workpiece edge is extended by a long cool-down period or delay, by interlacing a radiation beam scanning pattern. During the cool-down period, the beam successively scans (along the fast axis) two rows separated by about half the wafer diameter, and travels back and then forth (along the slow axis) across the distance between the two rows, while the radiation beam source continuously generates the beam.
