  • Patent number: 11035033
    Abstract: The present disclosure enables high-resolution direct patterning of a material on a substrate by establishing and maintaining a separation between a shadow mask and a substrate based on the thickness of a plurality of standoffs. The standoffs function as a physical reference that, when in contact between the substrate and shadow mask determine the separation between them. Embodiments are described in which the standoffs are affixed to an element selected from the shadow mask, the substrate, the mask chuck, and the substrate chuck.

  • Patent number: 10964889
    Abstract: A deposition mask includes a first area defining a clamping portion at ends of the deposition mask and to which a force is applied to extend the deposition mask in a length direction thereof, a recess area adjacent to the first area and defining a recess at the ends; and a pattern portion including a plurality of pattern holes through which a deposition material passes. Along the length direction, a plurality of first pattern portions are arranged in the first area and a plurality of second pattern portions arranged in the recess area. The force applied extends the first area and does not extend the recess area. The force not applied defines non-extended positions of the pattern portions, and for the non-extended positions of the first and second pattern portions, a first distance between adjacent first pattern portions is less than a second distance between adjacent second pattern portions.
