Abstract: A method includes forming a first fin and a second fin protruding from a frontside of a substrate, forming a gate stack over the first and second fins, forming a dielectric feature dividing the gate stack into a first segment engaging the first fin and a second segment engaging the second fin, and growing a first epitaxial feature on the first fin and a second epitaxial feature on the second fin. The dielectric feature is disposed between the first and second epitaxial features. The method also includes performing an etching process on a backside of the substrate to form a backside trench, and forming a backside via in the backside trench. The backside trench exposes the dielectric feature and the first and second epitaxial features. The backside via straddles the dielectric feature and is in electrical connection with the first and second epitaxial features.

Abstract: A flow guiding device in an immersion-cooled chassis of a server comprises at least one deflector located above a chip on a mainboard in the chassis, each deflector comprises a first end for mounting to the mainboard above the chip and a second end inclined away from the mainboard. The first end is immersed in coolant, the second end is higher than the first end; the deflector further comprises a hollow part including multiple through holes for interrupting upward movement vapor bubbles generated by the hot chip, which reduces probability of the vapor bubbles escaping from the coolant liquid and the chassis. A liquid-cooled chassis having the flow guiding device is also disclosed.

Abstract: A manifold for cooling server includes an inlet pipe, an outlet pipe, a plurality of first hole groups, and a plurality of second hole groups. The distance between every two adjacent first hole groups is first distance, the distance between every two adjacent second hole groups is second distance, and the first distance is not equal to the second distance. The first distance is designed for one size of server, and the second distance is designed for another size of server. When changing the size of all servers in the rack, turning manifold 100 to 180 degrees to change the first hole groups 30 to the second hole groups 40 for adapting the severs, which makes the manifold 100 adapt two different sizes of server. A rack and a data center cooling system using the manifold are also disclosed.

Abstract: A recovery layer (e.g., a layer of organic and/or tin-based material) is formed within recesses, in which adjacent MEOL or BEOL structures are formed, after plasma ashing and before a trimming process. The recovery layer preserves hardmask material and dielectric material such that upper surfaces of the adjacent MEOL or BEOL structures remain physically separated. As a result, the adjacent MEOL or BEOL remain electrically isolated and functional.
