  • Publication number: 20240372344
    Abstract: A power supply has a housing, a circuit board, a wire, and a wire securing assembly. The wire securing assembly has a base plate and a securing structure. The securing structure has a first plate and a second plate. A side edge of the first plate is connected to the base plate. The second plate is spaced apart from the first plate. The wire is mounted through and between the first plate and the second plate. The wire securing assembly is modified from the current insulating part, in which the original side plate extends and forms an additional part, or a bent structure is added on the original side plate, and thus the additional structures become the securing structure. Thus, the wire is prevented from moving under vibration or external force and contacting the blades of the fan, or keeps in a position in compliance with safety requirements.

    Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.
