Abstract
A stamp donor plate includes a stamp donor plate substrate including an inner area and an outer area surrounding the inner area; and a stamp structure disposed on the stamp donor plate substrate, wherein the stamp structure includes a plurality of protrusions, wherein the plurality of protrusions include a plurality of first protrusions arranged on an inner area, and a plurality of second protrusions arranged on the outer area.
Claims13
A stamp donor plate comprising:
- a stamp donor plate substrate including an inner area and an outer area surrounding the inner area;
- and
- a stamp structure disposed on the stamp donor plate substrate,
- wherein the stamp structure includes a plurality of protrusions including a plurality of first protrusions arranged on the inner area and a plurality of second protrusions arranged on the outer area,
- wherein each of the plurality of protrusions has a first surface in contact with the stamp donor plate substrate and a second surface opposite to the first surface,
- wherein a width of the second surface is larger than a width of the first surface, and
- wherein the second surface of the protrusions adjacent to each other contact each other at a boundary therebetween.
