Abstract: Embodiments described herein may be related to apparatuses, processes, systems, and techniques directed to electrical couplings between epitaxial structures and voltage sources within transistors in SRAM bit cells. Embodiments include direct electrical couplings between a backside contact metal (BMO) and a backside of an epitaxial structure to provide SRAM VCC voltage (SVCC) voltage, as well as electrical connection structures that electrically couple the BMO to a front side of an epitaxial structure to provide SVCC voltage. Other embodiments may be described and/or claimed.

Abstract: Lithographic apparatuses suitable for complementary e-beam lithography (CEBL) are described. In an example, a method of forming a pattern for a semiconductor structure includes forming a pattern of parallel lines above a substrate. The method also includes aligning the substrate in an e-beam tool to provide the pattern of parallel lines parallel with a scan direction of the e-beam tool. The e-beam tool includes a column having a blanker aperture array (BAA) with a staggered pair of columns of openings along an array direction orthogonal to the scan direction. The method also includes forming a pattern of cuts or vias in or above the pattern of parallel lines to provide line breaks for the pattern of parallel lines by scanning the substrate along the scan direction. A cumulative current through the column has a non-zero and substantially uniform cumulative current value throughout the scanning.

Abstract: Integrated circuit structures having differentiated interconnect lines in a same dielectric layer, and methods of fabricating integrated circuit structures having differentiated interconnect lines in a same dielectric layer, are described. In an example, an integrated circuit structure includes an inter-layer dielectric (ILD) layer above a substrate. A plurality of conductive interconnect lines is in the ILD layer. The plurality of conductive interconnect lines includes a first interconnect line having a first height, and a second interconnect line immediately laterally adjacent to but spaced apart from the first interconnect line, the second interconnect line having a second height less than the first height.

Abstract: Embodiments herein describe techniques for a semiconductor device having an interconnect structure above a substrate. The interconnect structure may include an inter-level dielectric (ILD) layer and a separation layer above the ILD layer. A first conductor and a second conductor may be within the ILD layer. The first conductor may have a first physical configuration, and the second conductor may have a second physical configuration different from the first physical configuration. Other embodiments may be described and/or claimed.
