  • Publication number: 20090089736
    Abstract: An embodiment provides systems and techniques for determining an improved process model which models mask corner rounding (MCR) effects. During operation, the system may receive a mask layout and process data which was generated by applying a photolithography process to the mask layout. The system may also receive an uncalibrated process model which may contain a set of MCR components. Next, the system may identify a set of corners in the mask layout. The system may then modify the mask layout in proximity to the set of corners to obtain a modified mask layout. Alternatively, the system may determine a set of mask layers. Next, the system may determine an improved process model by calibrating the uncalibrated process model using the modified mask layout and/or the set of mask layers, and the process data.

  • Publication number: 20090042113
    Abstract: A manufacturing method of a filter is provided. The manufacturing method includes steps as follows. First, a substrate is provided and a black matrix is formed on the substrate. The black matrix has a number of openings arranged in array. Next, a filter material is individually formed in the openings by inkjet printing or other methods, and the filter material includes a solvent and a dye mixed with the solvent. Thereafter, a thermal treatment is performed and an evaporation rate of the solvent during the thermal treatment is reduced, so as to cure the filter material. As the evaporation rate of the solvent is relatively slow, the filter material is still flowable during the thermal treatment. Hence, the cured filter material has a flat surface. The filter fabricated by the above manufacturing method has an even hue and a well flattened surface.
