Abstract:
The present disclosure relates to semiconductor structures and, more particularly, to interrupted small block shape structures (e.g., cut metal lines forming cell boundaries) and methods of manufacture. The structure includes: a plurality of wiring lines with cuts that form a cell boundary; and at least one wiring line extending beyond the cell boundary and which is continuous from cell to cell.

Claim (Index 19):
A method comprising:\n defining a pattern in a first mask over a dielectric material, comprising:\n depositing a block material on the dielectric material; \n patterning the block material with a lithography step to form an outline of a cell boundary and a notched shape having a dimension of at least a width of a metal line; \n forming a material over the patterned block material and within the notched feature; \n anisotropically etching the material to form an overhang on the block material and covering a portion of the notched feature; \n etching exposed portions of the block material with the overhang protecting the dielectric material and block material underneath the overhang from being etched; \n removing the overhang leaving the pattern in the first mask having a width dimension of the overhang; \n defining a pattern in a second mask, superimposed over the pattern of the first mask; etching a layout within the dielectric material corresponding to the superimposed pattern of the second mask, with the first mask protecting the dielectric material from being etched; and filling the layout with metal material to form at least cut wiring structures defining a cell boundary defined by the pattern in the first mask.
