  • Patent number: 7530749
    Abstract: A coating and developing system prevents wetting its component units with water when the coating and developing system forms a resist film on a substrate and processes the substrate processed by immersion exposure by a developing process. A substrate having a surface coated with a resist film and processed by immersion exposure is placed on a substrate support device and a liquid detector detects at least the liquid formed a liquid film for immersion exposure and remaining on the surface of the substrate. A decision is made as to whether or not the substrate needs to be dried on the basis of the result of detection made by the liquid detector. If it is decided that the substrate needs to be dried, the substrate is dried by a drying means. Thus wetting the interior of the coating and developing system with water can be prevented. Since only substrates that need to be dried are subjected to a drying process, the coating and developing system is able to operate at a high throughput.

  • Publication number: 20090097000
    Abstract: A lithography method is proposed employing a projection exposure system having a catoptric imaging optics comprising a mirror formed as phase mask in the imaging beam path, wherein the mirror formed as phase mask exhibits continuous regions having dielectric layers provided thereon. Optionally, the regions of the mirror formed as phase mask are configured such that an axial extension of an image of a point (DOF) of the imaging is increased or/and a lateral extension of an image of a point of the imaging is decreased. Preferably multiple exposures of a same radiation sensitive substrate are performed in order to achieve an increase in resolution and scaling down of the manufacturing trace structures (61, 61?), respectively.

  • Publication number: 20090079948
    Abstract: A developing method is used for subjecting a light-exposed resist film disposed on a wafer W to a developing process by a developing solution and a rinsing process by a rinsing liquid. In a state where the resist film on the wafer W is wet with the developing solution or rinsing liquid before a drying process is performed on the wafer W, a chemical liquid (curing chemical liquid), which contains a resist curing aid contributory to curing of a resist film remaining on the wafer W, is supplied onto a surface of the wafer W. Then, ultraviolet rays are radiated onto a surface of the wafer to cure a resist film remaining on the wafer W by a synergistic effect of the resist curing aid and the ultraviolet rays thus radiated, so as to prevent pattern fall.

  • Publication number: 20090073394
    Abstract: After a substrate is cleaned, a liquid supply nozzle moves outward from above the center of the substrate while discharging a rinse liquid with the substrate rotated. In this case, a drying region where no rinse liquid exists expands on the substrate. When the liquid supply nozzle moves to above a peripheral portion of the substrate, the rotational speed of the substrate is reduced. The movement speed of the liquid supply nozzle is maintained as it is. Thereafter, the discharge of the rinse liquid is stopped while the liquid supply nozzle moves outward from the substrate. Thus, the drying region spreads over the whole substrate so that the substrate is dried.
