Abstract: A semiconductor cell includes a substrate and an array of at least five substantially parallel fins having substantially equal fin widths disposed on the substrate. The array includes a predetermined minimum spacing distance between at least one pair of adjacent fins within the array. The array has a first n-type fin for an n-type semiconductor device, and a first p-type fin for a p-type semiconductor device. The first p-type fin is disposed adjacent the first n-type fin and spaced a predetermined first n-to-p distance apart from the first n-type fin. The first n-to-p distance is greater than the minimum spacing distance and less than the sum of the fin width plus twice the minimum spacing distance.

Abstract: Devices and methods of fabricating integrated circuit devices for forming assymetric line/space with barrierless metallization are provided. One method includes, for instance: obtaining an intermediate semiconductor device having a substrate, a dielectric matrix, and a hardmask, the dielectric matrix including a set of trenches etched into the dielectric matrix and a set of dielectric fins comprising the dielectric matrix, wherein the set of trenches and the set of dielectric fins are of equal width; damaging an inner surface of each trench of the set of trenches; etching the damaged material of the trenches removing the damaged material of the dielectric matrix; removing the hardmask; and metallizing the trenches by depositing a metal directly on the dielectric matrix with no barrier between the metal and the dielectric matrix after the etching. Also disclosed is an intermediate device formed by the method.

Abstract: A method includes patterning a 1st mandrel cell into a 1st mandrel layer disposed above a dielectric layer of a semiconductor structure. The 1st mandrel cell has 1st mandrels, 1st mandrel spaces and a mandrel cell pitch. A 2nd mandrel cell is patterned into a 2nd mandrel layer disposed above the 1st mandrel layer. The 2nd mandrel cell has 2nd mandrels, 2nd mandrel spaces, and the mandrel cell pitch. The 1st and 2nd mandrel cells are utilized to form metal line cells into the dielectric layer. The metal line cells have metal lines, spaces between the metal lines and a line cell pitch. The line cell pitch is equal to the mandrel cell pitch when the metal lines of the metal line cells are an even number. The line cell pitch is equal to half the mandrel cell pitch when the metal lines of the metal line cells are an odd number.

Abstract: A method includes providing a semiconductor structure having a mandrel layer and a hardmask layer disposed above a dielectric layer. A mandrel cell is patterned into the mandrel layer. An opening is etched into the hardmask layer. The opening is self-aligned with a sidewall of the mandrel. A refill layer is disposed over the structure and recessed down to a level that is below a top surface of the hardmask layer to form an opening plug that covers a bottom of the opening. The mandrel cell is utilized to form a metal line cell into the dielectric layer, the metal line cell having metal lines and a minimum line cell pitch. The opening plug is utilized to form a continuity cut in a metal line of the metal line cell. The continuity cut has a length that is larger than the minimum line cell pitch.
