    Abstract: 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.

    Abstract: A method of fabricating a semiconductor-on-insulator structure from a pair of semiconductor wafers, includes forming an oxide layer on at least a first surface of a first one of the wafers and performing a bonding enhancement implantation step by ion implantation of a first species in the first surface of at least either of the pair of wafers. The method further includes performing a cleavage ion implantation step on one of the pair of wafers by ion implanting a second species to define a cleavage plane across a diameter of the wafer at the predetermined depth below the top surface of the one wafer. The wafers are then bonded together by placing the first surfaces of the pair of wafers onto one another so as to form an semiconductor-on-insulator structure. The method also includes separating the one wafer along the cleavage plane so as to remove a portion of the one wafer between the second surface and the cleavage plane, whereby to form an exposed cleaved surface of a remaining portion of the one wafer on the semiconductor-on-insulator structure. Finally, the cleaved surface is smoothed, preferably by carrying out a low energy high momentum ion implantation step.

    Abstract: A plasma etching process, particularly useful for selectively etching oxide over a feature having a non-oxide composition, such as silicon nitride and especially when that feature has a corner that is prone to faceting during the oxide etch. A primary fluorine-containing gas, preferably hexafluorobutadiene (C4F6), is combined with a significantly larger amount of the diluent gas xenon (Xe) enhance nitride selectivity without the occurrence of etch stop. The chemistry is also useful for etching oxides in which holes and corners have already been formed, for which the use of xenon also reduces faceting of the oxide. For this use, the relative amount of xenon need not be so high. The invention may be used with related heavy fluorocarbons and other fluorine-based etching gases.
