    摘要: A method of fabricating substrates, e.g., bulk wafers, silicon on insulator wafers, silicon on saphire, optoelectronic substrates. The method includes providing a substrate (e.g., silicon, gallium arsenide, gallium nitride, quartz). The substrate has a film characterized by a non-uniform surface, which includes a plurality of defects. At least some of the defects are of a size ranging from about 100 Angstroms and greater. The method also includes applying a combination of a deposition species for deposition of a deposition material and an etching species for etching etchable material. The combination of the deposition species and the etching species contact the non-uniform surface in a thermal setting to reduce a level of non-uniformity of the non-uniform surface by filling a portion of the defects to smooth the film of material. The smoothed film of material is substantially free from the defects and is characterized by a surface roughness of a predetermined value.

    摘要: In a specific embodiment, the present invention provides a novel process for smoothing a surface of a separated film. The present process is for the preparation of thin semiconductor material films. The process includes a step of implanting by ion bombardment of the face of the wafer by means of ions creating in the volume of the wafer at a depth close to the average penetration depth of the ions, where a layer of gaseous microbubbles defines the volume of the wafer a lower region constituting a majority of the substrate and an upper region constituting the thin film. A temperature of the wafer during implantation is kept below the temperature at which the gas produced by the implanted ions can escape from the semiconductor by diffusion. The process also includes contacting the planar face of the wafer with a stiffener constituted by at least one rigid material layer. The process includes treating the assembly of the wafer and the stiffener at a temperature above that at which the ion bombardment takes place and adequate to create by a crystalline rearrangement effect in the wafer and a pressure effect in the microbubbles to create separation between the thin film and the majority of the substrate. The stiffener and the planar face of the wafer are kept in intimate contact during the stage to free the thin film from the majority of the substrate. The method also includes applying a combination of thermal treatment and an etchant to the thin film to reduce a surface roughness of the thin film to a predetermined value.

    摘要: Processing of substrates in a CVD reactor system wherein tungsten silicide is deposited is accomplished with preflow and postflow of reducing gases before and after deposition steps to ensure that tungsten-rich film is not deposited at the interface of the tungsten silicide film to the substrates or on the tungsten silicide film at the end of deposition processing. For systems having a remote gas injection and flow control system connected by a gas supply manifold to a CVD reactor chamber, an isolation valve is provided in the gas supply manifold, and the valve is held closed during at least a portion of time between deposition sequences.

    摘要: A system for depositing a film on a substrate in a CVD process has a second-source injection sub-system for injecting a control gas. The deposition rate of the material deposited in the CVD process is a function of the concentration of the control gas at the point that material is deposited. The second source injection sub-system provides a concentration gradient of the control gas relative to the substrate surface coated, and alters the thickness uniformity of the film. By controlling the gradient one may control the thickness uniformity profile. In another embodiment, the invention applies to dry etching with reactive gas, and the etching rate is controlled by second source provision of a control gas.
