Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a fin. A first isolation structure separates a first end of a first portion of the fin from a first end of a second portion of the fin, the first end of the first portion of the fin having a depth. A gate structure is over the top of and laterally adjacent to the sidewalls of a region of the first portion of the fin. A second isolation structure is over a second end of a first portion of the fin, the second end of the first portion of the fin having a depth different than the depth of the first end of the first portion of the fin.

Abstract: A nanowire device having a plurality of internal spacers and a method for forming said internal spacers are disclosed. In an embodiment, a semiconductor device comprises a nanowire stack disposed above a substrate, the nanowire stack having a plurality of vertically-stacked nanowires, a gate structure wrapped around each of the plurality of nanowires, defining a channel region of the device, the gate structure having gate sidewalls, a pair of source/drain regions on opposite sides of the channel region; and an internal spacer on a portion of the gate sidewall between two adjacent nanowires, internal to the nanowire stack. In an embodiment, the internal spacers are formed by depositing photo-definable spacer material in dimples etched adjacent to the channel region. Photo-definable material remains in the dimples by altering the etch characteristics of material outside of the dimples and selectively removing altered photo-definable material outside of the dimples.

Abstract: Conductive via and metal line end fabrication is described. In an example, an interconnect structure includes a first inter-layer dielectric (ILD) on a hardmask layer, where the ILD includes a first ILD opening and a second ILD opening. The interconnect structure further includes an etch stop layer (ESL) on the ILD layer, where the ESL includes a first ESL opening aligned with the first ILD opening to form a first via opening, and where the ESL layer includes a second ESL opening aligned with the second ILD opening. The interconnect structure further includes a first via in the first via opening, a second ILD layer on the first ESL, and a metal line in the second ILD layer, where the metal line is in contact with the first via, and where the metal line includes a first metal opening, and where the metal line includes a second metal opening aligned with the second ILD opening and the ESL opening to form a second via opening. The interconnect structure further includes a metal line end in the first metal opening and further includes a second via in the metal line, where the second via is in the second via opening.
