Transmission control protocol (TCP) based control of a wireless user device
In a wireless communication network, a Transmission Control Protocol (TCP) optimization engine receives user data. The TCP optimization engine transfers a TCP packet having the user data to wireless User Equipment (UE). The UE wirelessly receives the TCP packet using a wireless communication protocol and loads the TCP packet into a TCP buffer. The UE generates a TCP Acknowledgment (ACK) for the TCP packet that also indicates the wireless communication protocol. The UE wirelessly transfers the TCP ACK to the TCP optimization engine. The TCP optimization engine selects a new size for the TCP buffer based on the wireless communication protocol in the TCP ACK from the UE. The TCP optimization engine generates and transfers a TCP buffer instruction to the UE indicating the buffer size. The UE wirelessly receives the TCP buffer instruction and sizes the TCP buffer to the TCP buffer size. |

Method of rounding corners of a fin
A method of rounding corners of a fin includes providing a substrate with a fin protruding from the substrate, wherein a pad oxide and a pad nitride entirely cover a top surface of the fin. Later, part of the pad oxide is removed laterally to expose part of the top surface of the fin. A silicon oxide layer is formed to contact two sidewalls of the fin and the exposed top surface, wherein two sidewalls and the top surface define two corners of the fin. After forming the silicon oxide layer, an annealing process is performed to round two corners of the fin. Finally, after the annealing process, an STI filling material is formed to cover the pad nitride, the pad oxide and the fin. |

Circuits employing a double diffusion break (DDB) and single diffusion break (SDB) in different type diffusion region(s), and related fabrication methods
Aspects disclosed herein include circuits employing a double diffusion break (DDB) and a single diffusion break (SDB) in different type diffusion regions, and related fabrication methods are disclosed.
