  • Patent number: 11365471
    Abstract: In a method of manufacturing a one-dimensionally varying optical filter, a substrate is coated to form a stack of layers of two or more different types. The coating may, for example, employ sputtering, electron-beam evaporation, or thermal evaporation. During the coating, the time-averaged deposition rate is varied along an optical gradient direction by generating reciprocation between a shadow mask and the substrate in a reciprocation direction that is transverse to the optical gradient direction. In some approaches, the shadow mask is periodic with a mask period defined along the direction of reciprocation, and the generated reciprocation has a stroke equal to or greater than the mask period along the direction of reciprocation. The substrate and the shadow mask may also be rotated together as a unit during the coating. Also disclosed are one-dimensionally varying optical filters, such as linear variable filters, made by such methods.

  • Patent number: 11353894
    Abstract: A liquid processing apparatus includes: a substrate processing unit; a supply line that supplies the fluid to the substrate processing unit; a flow meter that measures a flow rate of the fluid flowing through the supply line; a flow rate adjustment mechanism that adjusts the flow rate of the fluid flowing through the supply line; and a controller that control the flow rate adjustment mechanism based on a measurement result of the flow meter. The controller receives the measurement result at a first cycle. When the measurement result of the flow meter indicates that the flow rate of the fluid flowing through the supply line is included in a preset range, the controller causes the flow rate adjustment mechanism to adjust the flow rate of the fluid flowing through the supply line at a cycle having a time interval longer than a time interval of the first cycle.

  • Patent number: 11275315
    Abstract: A direct-deposition system forming a high-resolution pattern of material on a substrate is disclosed. Vaporized atoms from an evaporation source pass through a pattern of through-holes in a shadow mask to deposit on the substrate in the desired pattern. The shadow mask is held in a mask chuck that enables the shadow mask and substrate to be separated by a distance that can be less than ten microns. Prior to reaching the shadow mask, vaporized atoms pass through a collimator that operates as a spatial filter that blocks any atoms not travelling along directions that are nearly normal to the substrate surface. Vaporized atoms that pass through the shadow mask exhibit little or no lateral spread after passing through through-holes and the material deposits on the substrate in a pattern that has very high fidelity with the through-hole pattern of the shadow mask.
