  • Patent number: 11938511
    Abstract: A coating method includes supplying a film forming liquid onto a center of a front surface of a substrate from a nozzle in a state that a distance between the front surface and the nozzle is maintained at a coating distance; rotating the substrate at a first rotation speed in a period during which the film forming liquid is supplied onto the front surface, to allow the film forming liquid to be diffused toward an edge of the substrate from an outer periphery of the nozzle; and rotating the substrate at a second rotation speed after the supplying of the film forming liquid is stopped, to allow the film forming liquid to be further diffused. The coating distance is set to allow the film forming liquid to be kept between the nozzle and the front surface when a discharge of the film forming liquid is stopped.

  • Patent number: 11065639
    Abstract: A method for coating a top of a substrate with a coating solution includes supplying, before a solution film of the coating solution formed on the substrate dries, a solvent for the coating solution to a peripheral portion on the solution film of the coating solution on the substrate while rotating the substrate at a predetermined rotation speed to form a mixed layer of the coating solution and the solvent at the peripheral portion. The method includes, then, controlling a film thickness of the coating solution after drying by rotating the substrate at a rotation speed higher than the predetermined rotation speed to push the mixed layer to an outer peripheral side.

  • Patent number: 10666726
    Abstract: In a server (10), all column data items are extracted from a master data storage unit (11) and sent to a client (20) in addition to target data corresponding to a data acquisition request that has been sent from the client (20), and in the client (20), the target data and data items received from the server (10) are displayed on a screen in a user-interface selectable mode, thereby making it possible to download from the server (10) to the client (20) the minimum target data required when attempting to perform a desired process on the client (20), and doing away with the waste associated with downloading all the data. In addition, by also downloading and displaying in a selectable manner on a screen data items pertaining to data other than the target data, a user can be shown, in an operable-like manner, data items pertaining to actual data without downloading the actual data.

  • Publication number: 20150186337
    Abstract: The present invention incorporates both a program and data into an electronic document in a state in which the program can be executed by using the data, thereby generating an electronic document having a program. According to the present invention having the structure described above, in the case in which the program is to be executed to process the data from various viewpoints and the respective processing results are to be presented as electronic documents, it is not necessary to generate an electronic document in a state in which all of the respective processing results are output in advance. Consequently, it is possible to prevent an increase in the number of pages of the electronic document. Moreover, it is not necessary to re-create an electronic document in order to include lacking processing result afterwards.

  • Patent number: 6620244
    Abstract: When a resist film is formed by discharging a resist solution onto the front face of a wafer housed in a cup, a relation between the film thickness of a resist film and the line width of a circuit pattern when the resist film is exposed into a predetermined pattern and thereafter developed is obtained in advance, from that relation, a line width with less variations corresponding to the changes in film thickness of the resist film is selected from among line widths within a designated region to form a resist film to have the film thickness corresponding to the selected line width. Accordingly, the line width of the circuit pattern after development is not likely to vary regardless of the changes in film thickness of the resist film formed on the wafer.
