Claim 8:
9. A method for forming a patterned layer of a first material on a substrate, wherein the method comprises:
establishing a first alignment between a shadow mask and the substrate, wherein the shadow mask comprises;
(1) a first plurality of apertures that is arranged in a first arrangement that defines an aperture pattern having:
(i) an array of fields, each field being standoff-free and including a two-dimensional array of apertures of the first plurality thereof; and
(ii) a plurality of lanes, each lane being aperture free;
wherein the plurality of lanes is arranged in a two-dimensional arrangement such that each pair of adjacent fields of the plurality thereof is separated by a different lane of the plurality thereof and each lane resides between two fields of the array thereof; and

(2) a first plurality of standoffs affixed to the shadow mask, each standoff of the first plurality of standoffs having a first height that establishes a first separation between the shadow mask and the substrate when the shadow mask and substrate are in contact, wherein each standoff of the plurality thereof is located only on the shadow mask and is capable of being removed from contact with the substrate, and wherein the first plurality of standoffs is arranged in a two-dimensional arrangement such that at least one standoff of the first plurality thereof is affixed to the shadow mask within each lane of the plurality thereof; and

depositing the first material onto the substrate through the shadow mask.
