Abstract: A low-k dielectric film is formed on an entire surface of a substrate having a pad region and a circuit region. A resist pattern is formed on the low-k dielectric film, and an opening is formed in the low-k dielectric film of the pad region using the resist pattern as a mask. A silicon oxide film having strength higher than the low-k dielectric film is formed in the opening by liquid-phase deposition. Wirings are formed in the silicon oxide film of the pad region and in the low-k dielectric film of the circuit region using the damascene method.

Abstract: After applying a film-forming composition containing a polysiloxane, a pore-forming agent, an onium salt, and a solvent onto a semiconductor substrate, the solvent is evaporated from the film-forming compositions in a first heat treatment. Then, a second heat treatment is carried out in an inert-gas atmosphere to promote the polymerization of the polysiloxane and thus form a polysiloxane resin film. Thereafter, a third heat treatment is carried out in an oxidizing-gas ambient to form pores in the polysiloxane resin film.

Abstract: A substrate having a film to be etched is held on a rotating stage. While rotating the substrate, a chemical solution containing an etchant is supplied onto the substrate from a nozzle. A lamp house with a drive unit is positioned so that the distance between the substrate and a glass window of the lamp house becomes 2 to 5 mm, the lamp house accommodating a lamp generating ultraviolet light. The ultraviolet light irradiates the film through the chemical solution. The ultraviolet light has a higher energy than the binding energy of constituent molecules of the film.

Abstract: A substrate supporting film to be etched is held on a rotating stage. Ultraviolet light having a wavelength of 200 nm or shorter radiated from first lamps irradiates the film in air, thereby removing organic coatings from the film and making the surface of the film hydrophilic. A chemical solution applied to the hydrophilic film while rotating the substrate. Ultraviolet light having a wavelength longer than 200 nm is radiated from second lamps and onto the film through the chemical solution.

Abstract: Each of patterns on two types of photomasks, including identical central pattern portions, each having a line pattern on the center of a substrate, and peripheral pattern portions around the central pattern portions, and having distances between the central pattern portion and the peripheral pattern portion different from each other, is transferred onto a wafer. Thereafter, each line width of the transferred patterns corresponding to the line pattern of each photomask is measured. The difference between each of line widths is obtained, from which the flare rate is calculated.

Abstract: A method for manufacturing a semiconductor device includes forming a first insulating film on a substrate, forming a second insulating film on the first insulating film, and forming a gate electrode on the second insulating film. Forming the second insulating film includes supplying film-forming materials and adsorbing the film-forming materials on the first insulating film, purging the film-forming materials that have not been adsorbed, supplying oxidants to oxidize the adsorbed film-forming materials, and purging the oxidants that have not contributed to oxidization. Forming the second insulating film is repeated in cycles, continuously, and the purging time of the oxidants in an initial number of the cycles is longer than the purging time of the oxidants in cycles following the initial number of cycles.

Hence, the wafer heat-treatment system reduces power consumption by heating lamps by carrying out an evacuating process before the high-temperature heat-treatment process, and shortens the time necessary for the cool down process by a pressurizing process that is carried out after the completion of the high-temperature heat-treatment process.

Abstract: In a method of manufacturing a thin film battery in a chamber, a target comprising LiCoO2 is provided on a magnetron cathode in the chamber, and a substrate is placed facing the target. A process gas is introduced into the chamber and the process gas is energized to form a plasma to sputter the target to deposit LiCoO2 on the substrate. An ion flux of from about 0.1 to about 5 mA/cm2 is delivered from the plasma to the substrate to enhance the crystallinity of the deposited LiCoO2 material on the substrate. The process gas is exhausted from the chamber. The target can also be made of other materials.
