    摘要: Methods and apparatus for forming a germanium containing film on a patterned substrate are described. The patterned substrate is a silicon, or silicon containing material, and may have a mask material formed on a surface thereof. The germanium containing material is formed selectively on exposed silicon in the recesses of the substrate, and an overburden of at least 50% is formed on the substrate. The germanium containing layer is thermally treated using pulsed laser radiation, which melts a portion of the overburden, but does not melt the germanium containing material in the recesses. The germanium containing material in the recesses is typically annealed, at least in part, by the thermal treatment. The overburden is then removed.

    摘要: In a laser annealing system for workpieces such as semiconductor wafers, a pyrometer wavelength response band is established within a narrow window lying between the laser emission band and a fluorescence emission band from the optical components of the laser system, the pyrometer response band lying in a wavelength region at which the optical absorber layer on the workpiece has an optical absorption coefficient as great as or greater than the underlying workpiece. A multi-layer razor-edge interference filter having a 5-8 nm wavelength cut-off edge transition provides the cut-off of the laser emission at the bottom end of the pyrometer response band.

    摘要: The present invention generally relates to an optical system that is able to reliably deliver a uniform amount of energy across an anneal region contained on a surface of a substrate. The optical system is adapted to deliver, or project, a uniform amount of energy having a desired two-dimensional shape on a desired region on the surface of the substrate. Typically, the anneal regions may be square or rectangular in shape. Generally, the optical system and methods of the present invention are used to preferentially anneal one or more regions found within the anneal regions by delivering enough energy to cause the one or more regions to re-melt and solidify.

    摘要: A patterned dielectric layer is evaluated by measuring reflectance of a region which has openings. A heating beam may be chosen for having reflectance from an underlying conductive layer that is several times greater than absorptance, to provide a heightened sensitivity to presence of residue and/or changes in dimension of the openings. Reflectance may be measured by illuminating the region with a heating beam modulated at a preset frequency, and measuring power of a probe beam that reflects from the region at the preset frequency. Openings of many embodiments have sub-wavelength dimensions (i.e. smaller than the wavelength of the heating beam). The underlying conductive layer may be patterned into links of length smaller than the diameter of heating beam, so that the links float to a temperature higher than a corresponding temperature attained by a continuous trace that transfers heat away from the illuminated region by conduction.

    摘要: Two more measurements are made on the same workpiece, during fabrication. Each measurement may be made employing a different process. The measurements are used together to determine a property of the workpiece. For example, multiple measurements from a first process are used with a predetermined value of the property of interest in a simulator to generate a simulated value of a signal to be measured in a second process. One or more such simulated values and a measured value are used to identify a value of the property of interest. When the workpiece's property is found to not match the specification, a process control parameter used in the workpiece's fabrication is adjusted, thereby to implement process control.

    摘要: An apparatus and method uses diffusive modulation (without generating a wave of carriers) for measuring a material property (such as any one or more of: mobility, doping, and lifetime) that is used in evaluating a semiconductor wafer. The measurements are carried out in a small area, for use on wafers having patterns for integrated circuit dice. The measurements are based on measurement of reflectance, for example as a function of carrier concentration. In one implementation, the semiconductor wafer is illuminated with two beams, one with photon energy above the bandgap energy of the semiconductor, and another with photon energy near or below the bandgap. The diameters of the two beams relative to one another are varied to extract additional information about the semiconductor material, for use in measuring, e.g. lifetime.

    摘要: An apparatus for thermally processing a substrate includes a first radiation source configured to heat a substrate and emit radiation at a heating wavelength, focusing optics configured to direct radiation from the first radiation source to the substrate, and a second radiation source configured to emit radiation at a second wavelength different from the heating wavelength and at a lower power than the first radiation source. Radiation from the second radiation source is directed onto the substrate. The apparatus further includes a first detector configured to receive reflected radiation at the second wavelength and a computer system configured to receive an output from the first detector and adjust a focus plane of the first radiation source relative to the substrate. The second radiation source is configured to have substantially the same focus plane as the first radiation source.
