  • Publication number: 20240128324
    Abstract: A field effect transistor includes a substrate having a transistor forming region thereon; an insulating layer on the substrate; a first graphene layer on the insulating layer within the transistor forming region; an etch stop layer on the first graphene layer within the transistor forming region; a first inter-layer dielectric layer on the etch stop layer; a gate trench recessed into the first inter-layer dielectric layer and the etch stop layer within the transistor forming region; a second graphene layer on interior surface of the gate trench; a gate dielectric layer on the second graphene layer and on the first inter-layer dielectric layer; and a gate electrode on the gate dielectric layer within the gate trench.

  • Patent number: 6839935
    Abstract: A system cleans a set of optical connectors. The system includes a fluid source, a vacuum source, a support member which defines a cleaning device edge, and a set of cleaning devices. Each cleaning device includes (i) a fluid intake member which connects to the fluid source, (ii) a fluid output member which connects to the vacuum source, and (iii) a cleaning head which connects to the fluid intake member and the fluid output member. Each cleaning device is disposed along the cleaning device edge of the support member. The set of cleaning devices is configured to (a) align over a set of optical interfaces of the set of optical connectors, (b) direct fluid (e.g., gas, gaseous snow, etc.) from the fluid source toward the set of optical interfaces, and (c) draw the directed fluid away from the set of optical interfaces and toward the vacuum source.
