Patent ID: 8215074

Claim:
A method of forming a nanoscale pattern on a substrate, said method comprising: forming a first template layer encompassing a predefined area on a substrate, wherein an entirety of a bottom surface of said first template layer is planar; patterning first openings, each having a shape of a regular hexagon, in said first template layer, wherein said first openings are arranged in a first hexagonal array; forming first nanoscale self-assembled self-aligned structures in said first openings; forming a second template layer encompassing said area on said first nanoscale self-assembled self-aligned structures; patterning second openings, each having a shape of said regular hexagon, in said second template layer, wherein said second openings are arranged in a second hexagonal array; forming second nanoscale self-assembled self-aligned structures in said second openings; forming a third template layer encompassing said area on said first and second nanoscale self-assembled self-aligned structures; patterning third openings, each having a shape of said regular hexagon, in said third template layer, wherein said third openings are arranged in a third hexagonal array; and forming third nanoscale self-assembled self-aligned structures in said third openings.
