Abstract:
1. A method of forming a nanoscale pattern on a substrate, said method comprising: forming a first recessed region having a bottom surface that contiguously extends between two parallel first lengthwise edges on a first layer on a substrate; forming a first nanoscale self-assembled self-aligned structure containing at least one first line having a first sublithographic width and having first line edges parallel to said two parallel first lengthwise edges of said first recessed region; forming a second layer as a blanket layer that contiguously extends over said first nanoscale self-assembled self-aligned structure and over said first layer, wherein said bottom surface and said two parallel first lengthwise edges are located at identical locations relative to said substrate after said forming of said second layer as upon formation of said first recessed region; forming a second recessed region having two parallel second lengthwise edges on said second layer, wherein an angle between said two parallel first lengthwise edges and said two parallel second lengthwise edges is greater than zero; and forming a second nanoscale self-assembled self-aligned structure containing at least one second line having a second sublithographic width and having second line edges parallel to said two parallel second lengthwise edges of said first recessed region.
