Abstract:
1. A stamp, comprising: self-assembled block copolymer material on a surface of a stamp substrate, the self-assembled block copolymer material comprising alternating lamellae perpendicular to the surface of the stamp substrate, one lamella of the alternating lamellae comprising a first block of the self-assembled block copolymer material and another lamella of the alternating lamellae comprising a second block of the self-assembled block copolymer material; a first ink material on the first block of the self-assembled block copolymer material, the first ink material including a first functional group configured to bind to the first block of the self-assembled block copolymer material, a second functional group configured to bind to a first region on a receptor substrate, and a spacer molecule linking the first functional group and the second functional group; and a second ink material on the second block of the self-assembled block copolymer material, the second ink material including a third functional group configured to bind to the second block of the self-assembled block copolymer material, a fourth functional group configured to bind to a second region on the receptor substrate, and a spacer molecule linking the third functional group and the fourth functional group.
