  • Publication number: 20050141891
    Abstract: In optical line width measurement performed using the scatterometry technique, the present invention measures the line width formed on a substrate more accurately than in the prior art. After a predetermined pattern is formed in a resist film on a substrate, the refractive index and the extinction coefficient of the resist film are measured. Based on the measured values, calculation is performed to obtain calculated light intensity distributions of reflected light reflected from a plurality of virtual patterns. The calculated light intensity distributions are stored, and their library is created. The substrate for which the refractive index and so on are measured is irradiated with light, and the light intensity distribution of its reflected light is measured.

  • Patent number: 6872512
    Abstract: A method of forming a resist pattern effectively controls the manner/style and the amount of modification of a resist pattern in its reflowing process, realizing a desired resist pattern with a desired accuracy even if the deformation amount of the resist pattern is increased in the reflowing process. A second layer is formed on a first layer and then, a first resist pattern is formed on the second layer. The second layer is selectively etched using the first resist pattern as a mask. Thereafter, wettability of at least part of an exposed area of the second or first layer from the first resist pattern is adjusted, thereby forming a wettability-adjusted part. The first resist pattern is modified in such a way as to extend to the wettability-adjusted area by reflowing the first resist pattern using an organic solvent, thereby forming a second resist pattern for selectively etching the first layer or the second layer.

  • Patent number: 6872670
    Abstract: A silylation treatment unit includes a chamber, a heating mechanism provided in this chamber for heating a substrate, a supplying mechanism for supplying a vapor including a silylation reagent into the chamber. The unit also has a substrate holder for holding the substrate in the chamber, in which an interval between the heating mechanism and the substrate is adjustable to at least three levels or more. The substrate is received such that it is least influenced by a heat in the chamber by maximizing the interval from the heating mechanism. The interval is brought comparatively closer to the heating mechanism to wait until the temperature inside the chamber obtains a high planer uniformity. The interval is brought further closer to the heating mechanism after a high planer uniformity is obtained such that a silylation reaction occurs.

  • Patent number: 6864971
    Abstract: A system and method for performing optical inspection of structures on the surface of a semiconductor wafer. The wafer surface is illuminated with a polychromatic light source. A multiple-charged couple-device (CCD) camera is positioned to capture light diffracted by the structures on the wafer surface at the first order of diffraction. The captured light is then separated into a plurality of component wavelengths which are directed onto the CCDs. A digital filter creates a plurality of digitized diffractive images of the wafer surface at different component wavelengths. The diffractive images may be integrated and analyzed to detect defects in the structures, or may be, analyzed individually. An image at a particular wavelength may be selected and analyzed by using the known grating pitch of the structures to calculate the wavelength.

    Abstract: Light exposure areas 103 and light masking areas 104 in a sole reticle are arrayed in alternation to one another in both the longitudinal and transverse directions. Substrate is exposed to light by multi-domain light exposure using this reticle so that the respective areas of the reticle exposed to light with respective shots A to B, B to C . . . , N to M are not adjacent to one another in the boundary portions of the reticle shifted for executing the respective shots, thus relaxing the difference in illuminance between the respective shots and the difference in finish of the boundary portions of the shots, such differences becoming imperceptible to human eyes upon displaying liquid crystal display apparatus.

  • Patent number: 6485203
    Abstract: A developing unit, a coating unit and a plurality of cooling plates are arranged in a process station which performs a resist coating and so on and a wafer is transferred among them by a substrate transfer device. The temperature of an area to where the wafer is transferred is detected by a temperature/humidity detector and the temperature of the wafer which is cooled by the cooling plates is adjusted accordingly based on a detected value so that the temperature of the wafer when transferred to the coating unit becomes a coating temperature of a processing solution. Thereby, the wafer is transferred to the coating unit while maintaining its temperature with high accuracy to be coated with a resist solution, so that a formation of an uneven processing due to the temperature change can be prevented and a uniform processing can be performed.
