    摘要: A semiconductor doping process which enhances the dopant incorporation achievable using the Gas Immersion Laser Doping (GILD) technique. The enhanced doping is achieved by first depositing a thin layer of dopant atoms on a semiconductor surface followed by exposure to one or more pulses from either a laser or an ion-beam which melt a portion of the semiconductor to a desired depth, thus causing the dopant atoms to be incorporated into the molten region. After the molten region recrystallizes the dopant atoms are electrically active. The dopant atoms are deposited by plasma enhanced chemical vapor deposition (PECVD) or other known deposition techniques.

    摘要: Thick adherent dielectric films deposited on plastic substrates for use as a thermal barrier layer to protect the plastic substrates from high temperatures which, for example, occur during laser annealing of layers subsequently deposited on the dielectric films. It is desirable that the barrier layer has properties including: a thickness of 1 &mgr;m or greater, adheres to a plastic substrate, does not lift-off when cycled in temperature, has few or no cracks and does not crack when subjected to bending, resistant to lift-off when submersed in fluids, electrically insulating and preferably transparent. The thick barrier layer may be composed, for example, of a variety of dielectrics and certain metal oxides, and may be deposited on a variety of plastic substrates by various known deposition techniques. The key to the method of forming the thick barrier layer on the plastic substrate is maintaining the substrate cool during deposition of the barrier layer. Cooling of the substrate maybe accomplished by the use of a cooling chuck on which the plastic substrate is positioned, and by directing cooling gas, such as He, Ar and N2, between the plastic substrate and the cooling chucks. Thick adherent dielectric films up to about 5 &mgr;m have been deposited on plastic substrates which include the above-referenced properties, and which enable the plastic substrates to withstand laser processing temperatures applied to materials deposited on the dielectric films.

    摘要: The manufacturing methodology to produce polycrystalline silicon in time and cost efficient manner uses a spatially selective crystallization approach to greatly reduce the amount of energy delivered to the work surface. The amorphous silicon film is subjected to laser radiation substantially exclusively at localized areas where TFTs are to be formed. The source of radiation is a copper vapor laser which produces a highly stable radiation in a visible spectrum with an energy sufficient to convert amorphous silicon into polysilicon in 1-3 shots. The optic system delivers the homogenized, conditioned and focused laser beam to the area of interest in a controlled manner. Single or multi-laser beam arrangements, as well as different shapes and sizes of laser beam spots are contemplated.
