  • Publication number: 20250203904
    Abstract: The present disclosure is directed to a structure of a gate-all-around field effect transistors (GAAFET) and a method of forming the structure. The structure includes a diffusion barrier structure in an S/D epitaxial structure of the GAAFET. The diffusion barrier structure is in contact with an NS layer of the GAAFET and extends over side surfaces of inner spacer structures adjacent to the NS layer. The diffusion barrier structure separates a high doping region of the S/D epitaxial structure from the NS layer and regions of the inner spacer structures close to the NS layer. The diffusion barrier structure prevents (or mitigates) dopants in the high doping region from diffusing into the NS layer and the inner spacer structures, preserving the integrity of the NS layer as a semiconducting channel of the GAAFET and avoiding a current crowding effect.

  • Patent number: 12301536
    Abstract: An AP sets up a data tunnel to a remote network and monitors a remote DHCP session between a client device and a remote DHCP server in the remote network. The remote DHCP server assigns a remote IP address to the client device, and communication between the client device and the remote network is based on the remote IP address. In response to determining completion of the remote DHCP session, the AP initializes a local DHCP session with a local DHCP server in a local network to obtain a local IP address for the client device. Communication between the client device and the local network is based on the local IP address. In response to detecting the client device roaming from the AP to a target AP, the AP forwards the remote and local IP addresses and session data of active sessions on the client device to the target AP.
