  • Publication number: 20120292799
    Abstract: According to one embodiment, a pattern forming method includes: applying a curing resin onto a substrate to be processed; bringing a pattern forming template having concave-convex shaped pattern grooves on the surface into contact with the curing resin, to fill the pattern groove with the curing resin; curing the curing resin; and releasing the pattern forming template from the curing resin, to form a pattern of the curing resin on the substrate to be processed. Further, in the pattern forming method, before application of the curing resin, positional information of a foreign object present on the substrate to be processed is measured and stored, and the foreign object is then removed based on the stored positional information of the foreign object.

  • Patent number: 8097169
    Abstract: A method for filtering a chemical in which a first chemical stored in a first tank is filtered by a filter and a second chemical obtained by the filtering is stored in a second tank has: adding the capture amounts corresponding to the individual first chemicals first to n-th stored in the first tank, and getting an added capture amount; and comparing the added capture amount and a predetermined limit capture amount of the filter, and exchanging the filter based on the comparison result.

  • Patent number: 7510341
    Abstract: A temperature calibration method for a baking apparatus comprising forming a photoresist film onto a substrate, forming a latent image of a dose monitor mark onto the photoresist film, preparing baking processing apparatuses, baking the substrate or another substrate by temperature settings performed every repeat of a series of the forming the resist film and the forming the latent image with each prepared baking apparatus, cooling the baking-processed substrate, measuring a length of the latent image of the dose monitor mark after the cooling or a length of a dose monitor mark which being obtained by developing the resist film, determining relationship between a temperature setting and an effective dose in advance, and calibrating temperature settings corresponding to the each baking processing apparatus to be obtained a predetermined effective dose on the basis of the determining relationship and the measured length corresponding to the each baking processing apparatus.
