摘要:
An interconnection between a sublithographic-pitched structure and a lithographic pitched structure is formed. A plurality of conductive lines having a sublithographic pitch may be lithographically patterned and cut along a line at an angle less than 45 degrees from the lengthwise direction of the plurality of conductive lines. Alternately, a copolymer mixed with homopolymer may be placed into a recessed area and self-aligned to form a plurality of conductive lines having a sublithographic pitch in the constant width region and a lithographic dimension between adjacent lines at a trapezoidal region. Yet alternately, a first plurality of conductive lines with the sublithographic pitch and a second plurality of conductive lines with the lithographic pitch may be formed at the same level or at different.
