Thin semiconductor foils can be formed using light reactive deposition. These foils can have an average thickness of less than 100 microns. In some embodiments, the semiconductor foils can have a large surface area, such as greater than about 900 square centimeters. The foil can be free standing or releasably held on one surface. The semiconductor foil can comprise elemental silicon, elemental germanium, silicon carbide, doped forms thereof, alloys thereof or mixtures thereof. The foils can be formed using a release layer that can release the foil after its deposition. The foils can be patterned, cut and processed in other ways for the formation of devices. Suitable devices that can be formed form the foils include, for example, photovoltaic modules and display control circuits.

An sp3 bond boron nitride expressed by general formula BN, and having a hexagonal 5H or 6H polygonal structure and a property that it emits ultraviolet radiation, and a method for producing such boron nitride. A method for producing such boron nitride can be a method in which a reaction mixed gas containing boron and nitrogen is diluted with a diluent gas and the diluted gas is introduced into a reaction vessel, ultraviolet radiation is applied to the surface of a substrate placed in the reaction vessel, the growing surface on the substrate, or the growth space near the growth surface, and thus boron nitride is produced, deposited, or grown on the substrate by vapor phase reaction. Such boron nitride is used as an electronic material of e.g., a light-emitting diode, for an ultraviolet solid laser, as an electron emitting material, and as a material for coating the surface of a cutting tool. The boron nitride emits light with a sharp peak near 225 nm, and can be a promising material for putting a solid ultraviolet laser into practical use.
摘要:
A process for forming metal oxides, including mixed metal oxides, in a dilute vapor phase at a temperature below approximately 350 degrees Fahrenheit. The resulting novel oxides can be formed as dense films or coatings with very high strain-to-crack values, or as nanoparticles, depending primarily upon the concentration of the reactants. The novel oxides are formed by the reaction in the vapor phase of reactive metal molecules with atomic oxygen. The reactions are instantaneous at room temperature, which permits this process to be applied to the formation of metal oxides on temperature sensitive substrates. The atomic oxygen and highly reactive metal containing molecules are generated by the application of an effective amount of ultraviolet radiation.
摘要:
An electrode (79, 329) for a ferroelectric electronic device (80, 317C) is formed on an SiO2 isolation layer (77, 324) by depositing an adhesion layer (98, 326), such as titanium, between about 25 ANGSTROM and 500 ANGSTROM thick, then a layer (81, 328) of a nobel metal, such as platinum, that is at least 10 times thicker than the adhesion layer. The electrode is then annealed at a temperature higher than the minimum oxide eutectic temperature of the adhesion layer. The electrode is moved into the annealing furnace at a ramp rate such that it reaches its anneal temperature in five minutes or less. The relative thinness of the adhesion layer and the quick ramp up of the anneal causes all the titanium to be tied up in the oxide before it can diffuse through the platinum, and prevents the formation of rutile phases of the titanium and defects such as voids and hillocks in the platinum, which can destabilize the electrode.
摘要:
A liquid precursor containing a metal is applied to a substrate, RTP baked, and annealed to form a layered superlattice material. Special polyoxyalkylated precursor solutions are designed to optimize polarizability of the corresponding metal oxide materials by adding dopants including stoichiometric excess amounts of bismuth and tantalum. The RTP baking process is especially beneficial in optimizing the polarizability of the resultant metal oxide.
摘要:
A precursor solution (P22) formed of a liquid polyoxyalkylated metal complex in a solvent is applied to a substrate in the formation of a metal oxide thin film (P26). The liquid thin film is baked (P28) in air to a temperature up to 500 DEG C while UV radiation having a wavelength ranging from 180 nm to 300 nm is applied. The thin film can be twice-baked at increasing temperatures while UV radiation is applied at one or both bakings. The film is then annealed (P32) at temperature ranging from about 700 DEG C to 850 DEG C to produce a thin-film solid metal oxide product. Alternatively, the UV radiation may be applied to the liquid precursor, the thin film may be annealed with UV radiation, or combinations of such applications of UV radiation to the precursor, to the thin film before or after baking, and/or UV annealing may be used.
