  • Publication number: 20230152686
    Abstract: Methods for removing haze defects from a photomask or reticle are disclosed. The photomask is placed into a chamber which includes a hydrogen atmosphere. The photomask is then exposed to radiation. The energy from the radiation, together with the hydrogen, causes decomposition of the haze defects. The methods can be practiced on-site and quickly, without the need for wet chemicals or the need to remove the pellicle before cleaning of the photomask. A device for conducting the methods is also disclosed herein.

  • Publication number: 20230008957
    Abstract: A photolithography exposure of a photoresist coating on a semiconductor wafer uses an optical projection system to form a latent image. The photolithography exposure further uses a mask with a set of multiple pattern focus (MPF) marks. Each MPF mark of includes features having different critical dimension (CD) sizes. The latent image is developed to form a developed photoresist pattern. Dimension sizes are measured of features of the developed photoresist pattern corresponding to the features of the MPF marks having different CD sizes. A spatial focus map of the photolithography exposure is constructed based on the measured dimension sizes. To determine the focal distance at an MPF mark, ratios or differences may be determined between the measured dimension sizes corresponding to the features of the MPF marks having different CD sizes, and the focal distance at the location of the MFP mark constructed based on the determined ratios or differences.

  • Patent number: 8906599
    Abstract: A method and system to improve scanner throughput is provided. An image from a reticle is projected onto a substrate using a continuous linear scanning procedure in which an entire column of die or cells of die is scanned continuously, i.e. without stepping to a different location. Each scan includes translating a substrate with respect to a fixed beam. While the substrate is translated, the reticle is also translated. When a first die or cell of die is projected onto the substrate, the reticle translates along a direction opposite the scan direction and as the scan continues along the same direction, the reticle then translates in the opposite direction of the substrate thereby forming an inverted pattern on the next die or cell. The time associated with exposing the substrate is minimized as the stepping operation only occurs after a complete column of cells is scanned.
