Patent number: 6656539Abstract: An element is deposited by flowing a gas through a solid donor compound that includes the element, and over a substrate. The flow of gas deposits a film of a few monolayers of donor compound on the substrate. An optical radiation source (e.g., a femtosecond laser) which produces optical radiation at an instantaneous intensity sufficient to cause non linear or otherwise enhanced interaction between optical radiation photons and the donor compound is used to decompose the donor compound and deposit the metal on the substrate. After an initial deposit of the donor compound is produced, optical radiation can be absorbed and heat the substrate in the localized area of the deposit in order to accelerate the deposition process by thermally decomposing the donor compound.Type: GrantFiled: November 13, 2000Date of Patent: December 2, 2003Assignee: International Business Machines CorporationInventors: Richard A. Haight, Peter P. Longo, Alfred Wagner

Patent number: 6635589Abstract: Silicon oxide films which are good as gate insulation films are formed by subjecting a silicon oxide film which has been formed on an active layer comprising a silicon film by means of a PVD method or CVD method to a heat treatment at 300-700° C. in a dinitrogen monoxide atmosphere, or in an NH3 or N2H4 atmosphere, while irradiating with ultraviolet light, reducing the hydrogen and carbon contents in the silicon oxide film and introducing nitrogen into the boundary with the silicon film in particular. Furthermore, silicon oxide films which are good as gate insulating films have been formed by subjecting silicon oxide films which have been formed on an active layer comprising a silicon film by means of a PVD method or CVD method to a heat treatment at 300-700° C. in an N2O atmosphere (or hydrogen nitride atmosphere) while irradiating with ultraviolet light, and then carrying out a heat treatment at 300-700° C.Type: GrantFiled: April 7, 1999Date of Patent: October 21, 2003Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei Yamazaki, Yasuhiko Takemura, Mitsunori Sakama, Tomohiko Sato, Satoshi Teramoto, Shigefumi Sakai

Patent number: 6461692Abstract: A method an apparatus for chemical vapor deposition for producing a thin film. The method includes the steps of: introducing a reactive gas into a reaction chamber wherein a substrate is supported in the reaction chamber; combining charged particles with a component of the reactive gas for ionizing the component; and electrostatically depositing the ionized component onto the substrate in an electric field. Charged particles may be photoelectrons or positive or negative ions produced by discharge. The reactive gas may be solely an ingredient gas containing a component for a thin film or a mixture of the ingredient gas and an oxidizing or reducing gas. The apparatus includes a reaction chamber including a support for a substrate, a device for introducing a reactive gas into the reaction chamber, an electric discharge device, and a device for forming an electric field in the reaction chamber in a direction to the support for the substrate, and an outlet for discharging the reactive gas.Type: GrantFiled: October 26, 1998Date of Patent: October 8, 2002Assignee: Ebara CorporationInventors: Toshiaki Fujii, Motoaki Adachi, Kikuo Okuyama

Patent number: 6416822Abstract: The present invention relates to an enhanced non-sequential atomic layer deposition (ALD) technique suitable for deposition of barrier layers, adhesion layers, seed layers, low dielectric constant (low-k) films, high dielectric constant (high-k) films, and other conductive, semi-conductive, and non-conductive films. This is accomplished by 1) providing a non-thermal or non-pyrolytic means of triggering the deposition reaction; 2) providing a means of depositing a purer film of higher density at lower temperatures; and, 3) providing a faster and more efficient means of modulating the deposition sequence and hence the overall process rate resulting in an improved deposition method.Type: GrantFiled: March 19, 2001Date of Patent: July 9, 2002Assignee: Angstrom Systems, Inc.Inventors: Tony P.
