Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method that prevents oxidation of an exposed metal-containing material of an integrated circuit when a part of silicon is selectively oxidized. SOLUTION: The silicon and metal-containing material are exposed portions of a partially-fabricated integrated circuit and may form part of, e.g., a transistor. The silicon and metal-containing material are oxidized in an atmosphere containing an oxidant and a reducing agent. In some embodiments, the reducing agent is present at a concentration of about 10 vol% or less. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a semiconductor processing apparatus having an improved thermal characteristic, and a method of providing the processing apparatus. SOLUTION: The semiconductor processing apparatus includes a process chamber containing a heated gaseous atmosphere. The apparatus includes many mechanical components, at least one of which is at least partially coated with heating/reflecting amorphous SiO 2 particles. The method of processing constituent elements of the semiconductor processing apparatus includes steps of: at least partially coating the surface of the constituent element with the amorphous SiO 2 particles; and sealing the coated surface of the constituent element.

Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor processing components having apertures with deposited coatings, and to provide a method for forming the same. SOLUTION: Holes 210 in semiconductor processing reactor components 200 are sized to facilitate deposition of protective coatings, such chemical vapor deposition at atmospheric pressure. In some embodiments, the holes 210 each have a flow constriction 212 that narrows the holes 210 in one part and that also divides the holes into one or more other parts. In some embodiments, the aspect ratios of the one or more other parts are about 15:1 or less, or about 7:1 or less, and have a cylindrical or conical cross-sectional shape. The holes 210 are coated with a protective coating, such as a silicon carbide coating, by chemical vapor deposition, including chemical vapor deposition at atmospheric pressure.

Abstract:
PROBLEM TO BE SOLVED: To provide a method in which advantages of an ALD mode and a CVD mode are combined with each other. SOLUTION: Atomic layer deposition (ALD) is used to deposit one layer and pulsed chemical vapor deposition (CVD) is used to deposit another layer. During the ALD part, sequential and alternating pulses of reactants are flowed. During the pulsed CVD part, two CVD reactants are flowed, with at least a first of the CVD reactants flowed in pulses, with those pulses overlapping at least partially with the flow of a second of the CVD reactants. In the present invention, e.g., nanolaminate films can be formed. Preferably, high quality layers are formed by flowing the second CVD reactant into a reaction chamber for a longer total duration than the first CVD reactant. In some embodiments, the pulses of the third reactant at separated by a duration at least about 1.75 times the length of the pulse. Preferably, less than about 8 monolayers of material are deposited per pulse of the first CVD reactant. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To prevent the bonding of a gas-phase reactant having unsaturated coordination to the other same molecule or sticking the gas-phase reactant to a reactor wall. SOLUTION: The present invention provides a method adapted to improve the deposition of a film on a substrate in a reaction chamber through a gas-phase deposition process (two or more reactants are supplied to the reaction chamber), wherein the method includes supplying a volatile neutral coordinating ligand to the reaction chamber (wherein the ligand can coordinate with at least one selected from (i) one of the reactants and (ii) a reaction by-product formed in the chamber during the film deposition process).

Abstract:
PROBLEM TO BE SOLVED: To provide a heat treatment apparatus which can control not only the temperature of a furnace body and the temperatures of a heating zone but also the thermal recovery rate of the furnace body after a substrate is placed in the vicinity of the furnace body. SOLUTION: Heat treatment is performed while making a substrate float between two heated surfaces of a reactor by flowing gas. The two heated surfaces have multiple heating zones, respectively. The heating rate of each heating zone is independently controlled by two nested control loops in a cascade temperature control configuration, permitting compensation for differences in the heating rates of the heating zones, thus allowing a uniform temperature or a predetermined temperature gradient to be established across all the heating zones. The intensity of transitional heating is recalculated after the introduction of each substrate by using the heating behavior of the previous transitional heating as an input in order to more accurately heat the heating zones to a desired temperature. As the intensity of transitional heating can be changed from one substrate to the other, the throughput of the heat treatment apparatus can also be changed. COPYRIGHT: (C)2005,JPO&NCIPI
