Abstract: There is described a method of forming a fine pattern aimed at depositing a silicon-nitride-based anti-reflection film which is stable even at high temperature and involves small internal stress. The method is also intended to preventing occurrence of a footing pattern (a rounded corner) in a boundary surface between a photoresist and a substrate at the time of formation of a chemically-amplified positive resist pattern on the anti-reflection film. The method includes the steps of forming a silicon-nitride-based film directly on a substrate or on a substrate by way of another layer; and forming a photoresist directly on the silicon-nitride-based film or on the silicon-nitride-based film by way of another layer. The silicon-nitride-based film is deposited while the temperature at which the substrate is to be situated is set so as to fall within the range of 400 to 700° C., through use of a plasma CVD system.

Abstract: Atmosphere inside a wafer carrier is purged through an open face of the wafer carrier, in the state where a carrier door constituting a face of the wafer carrier is opened by a load port door. Purging is carried out by partitioning a mini-environment with an upper wall surface, a lower wall surface, and an EFEM door into a predetermined space adjacent to the open face, by discharging gas from the predetermined space through an exhaust opening, and by supplying an inert gas or a dry air from a gas supply port into the predetermined space.

Abstract: In a load port mechanism of a substrate treatment unit, protuberances are provided on a sealing surface formed along a door with which a wafer carrier is to dock, or on a sealing surface formed around the door of the wafer carrier. The wafer carrier door is faced with the load port door with the protuberances therebetween, thereby separating the sealing surface of the substrate treatment unit from the sealing surface of the wafer carrier by only a predetermined distance. Thus, there is formed a channel along which clean air flows from the inside of the substrate treatment unit to the outside thereof. The load port structure and the wafer carrier structure improve the reliability of opening/closing action of the wafer carrier and prevent entry of extraneous particles into the treatment unit with sufficient reliability, and enable high-yield production of integrated circuits.

Abstract: A resist pattern is formed on a film to be processed using a lithography technique. The line width of the resist pattern is narrowed using a slimming technique. Thereafter, the pattern of a first film to be processed is formed in the space that has been widened by slimming, utilizing the phenomenon in which anisotropic etching under a reduced pressure accelerates the etching rate in the vicinity of the side of the line of the pattern compared to other areas. An underlying second film to be processed is etched using the first film to be processed as a mask. Thereby the pattern of the second film to be processed that has a pitch ½ the lithography pattern is formed.

Abstract: At least two elastic wave sensors are disposed in contact with a workpiece such as a microstructure or an optical structure. Elastic waves generated during chemical mechanical polishing of the workpiece are monitored by using the elastic wave sensors. Chemical mechanical polishing conditions are set to achieve uniform chemical mechanical polishing, or an ending point of the chemical mechanical polishing is set based on the monitored signal by the elastic wave sensors, and a process is carried out for chemical mechanical polishing. By the process, a workpiece is polished uniformly to flatten steps in the workpiece or to flatten surface defects of a structure. Alternatively, by the process, a workpiece having a laminated structure is polished up to an interface of the laminated structure.
