Abstract:
1. A method comprising: providing a shadow mask having a free-standing silicon nitride, silicon oxide, or aluminum oxide membrane; and forming a pattern of a first color emitter material on a substrate using the shadow mask, wherein the pattern of a first color emitter material has one or more first color emitter material structures having at least one dimension of less than 10 microns; forming a pattern of a second color emitter material on the substrate having the pattern of the first color emitter material using a second shadow mask having a free-standing silicon nitride, silicon oxide, or aluminum oxide membrane, wherein the pattern of the second color emitter material has one or more second color emitter material structures having at least one dimension of less than 10 microns; and forming a pattern of a third color emitter material on the substrate having the pattern of the first color emitter material and the pattern of the second color emitter material using a third shadow mask having a free-standing silicon nitride, silicon oxide, or aluminum oxide membrane, wherein the pattern of third color emitter material has one or more third color emitter material structures having at least one dimension of less than 10 microns.
