  • Patent number: 11121018
    Abstract: A reticle holding tool is provided. The reticle holding tool includes a housing, a reticle chuck, and a gas delivery assembly. The housing includes an opening, a top housing member, and a lateral housing member extending from the top housing member and terminating at a lower edge which is located on a predetermined plane. The reticle chuck is positioned in the housing and has an effective surface configured to secure a reticle. The effective surface is located between the predetermined plane and the top housing member. The reticle chuck is movable between two boundary lines that are perpendicular to the effective surface. A width of the opening is greater than a distance between the two boundary lines. The gas delivery assembly is positioned within the housing and configured to supply gas into the housing.

  • Patent number: 10999549
    Abstract: A column parallel ADC circuit includes: plural column ADCs and a digital processing circuit. The plural column ADCs generate respective plural digital counts. The plural column ADCs include a first column ADC and a second column ADC. The first column ADC generates a first digital count according to a first analog signal, and the second column ADC generates a second digital count according to a second analog signal. The first digital count is a difference between a first digital signal and a second digital signal. The first and the second digital signals correspond to the first and the second analog signals respectively. The digital processing circuit generates the plural digital signals, wherein the digital processing circuit generates the first digital signal according to the first digital count and the second digital signal.
