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.
