  • Publication number: 20200006157
    Abstract: Embodiments described herein relate to a method for patterning a doping layer, such as a lanthanum containing layer, used to dope a high-k dielectric layer in a gate stack of a FinFET device for threshold voltage tuning. A blocking layer may be formed between the doping layer and a hard mask layer used to pattern the doping layer. In an embodiment, the blocking layer may include or be aluminum oxide (AlOx). The blocking layer can prevent elements from the hard mask layer from diffusing into the doping layer, and thus, can improve reliability of the devices formed. The blocking layer can also improve a patterning process by reducing patterning induced defects.

  • Publication number: 20190378913
    Abstract: Embodiments described in this disclosure relate to formation of a gate structure of a device, such as in a replacement gate process, and the device formed thereby. In some examples, after an interfacial layer and a gate dielectric layer are deposited, a rapid anneal process, such as laser anneal or flash lamp anneal process, is performed in a controlled ambient nitrogen-containing environment to form a nitrided portion in the gate dielectric layer. The nitrided portion passivates the defects at the surface of the gate dielectric layer and can serve as a barrier to prevent etchant chemistry and defects/dopants from the subsequent gate stack layers from affecting or diffusing through the gate dielectric layer. Particularly, the rapid anneal process is performed on a millisecond scale to confine nitrogen atoms in the gate dielectric layer without diffusing into the underlying interfacial dielectric and/or any neighboring structure such as fin.

  • Patent number: 10492317
    Abstract: A latching structure includes a first plate, a second plate and a sliding plate disposed on a surface of the first plate and movable in a first direction. The first plate includes first arches each having an alignment hole in the first direction. The second plate includes second arches each having a latching hole in the first direction. The sliding plate includes pins corresponding to the latching holes. When the alignment hole accommodates the second arch and the sliding plate is located at a latching position, the pin is located in a corresponding latching hole to block separation of the first plate from the second plate in a second direction. When the sliding plate is located at a retracted position, the pin separates from the corresponding latching hole to allow separation of the first plate from the second plate in the second direction.

  • Publication number: 20190342219
    Abstract: In a network, communications between nodes in the network can be routed along different communication pathways. The network can include subnetworks provided and administered by third parties, and can include virtual private networks (VPNs), so that the different pathways can be or include VPN tunnels that pass through different subnetworks of the communications network. A central controller can monitor performance of the pathways, including those not in primary use, and dynamically adjust routing of communications traffic between the nodes by directing communication traffic to specific pathways or tunnels. The controller can direct different types of traffic (for example, data, voice) to particular pathways, and can direct traffic to different pathways based on direction of traffic flow (for example, uplink along one pathway and downlink along another pathway).
