Network interface device that sets an ECN-CE bit in response to detecting congestion at an internal bus interface
A network device includes a Network Interface Device (NID) and multiple servers. Each server is coupled to the NID via a corresponding PCIe bus. The NID has a network port through which it receives packets. The packets are destined for one of the servers. The NID detects a PCIe congestion condition regarding the PCIe bus to the server. Rather than transferring the packet across the bus, the NID buffers the packet and places a pointer to the packet in an overflow queue. If the level of bus congestion is high, the NID sets the packet's ECN-CE bit. When PCIe bus congestion subsides, the packet passes to the server. The server responds by returning an ACK whose ECE bit is set. The originating TCP endpoint in turn reduces the rate at which it sends data to the destination server, thereby reducing congestion at the PCIe bus interface within the network device. |

Plasma processing apparatus and plasma processing method
A plasma processing, apparatus of an embodiment includes a chamber, an introducing part, a first power source, a holder, an electrode, and a second power source. The introducing part introduces gas into the chamber. The first power source outputs a first voltage for generating ions from the gas. The holder holds a substrate. The electrode is opposite to the ions across the substrate, and has a surface not parallel to the substrate. The second power source applies a second voltage to the electrode. The second voltage has a frequency lower than the frequency of the first voltage and Introduces die ions to the substrate. |

Etching and structures formed thereby
Embodiments described herein relate generally to methods for etching structures and the structures formed thereby. In some embodiments, an etch selectivity between a first portion of a material and a second portion of the material is increased. Increasing the etch selectivity includes performing an anisotropic treatment, such as an anisotropic ion implantation, on the material to treat the first portion of the material, and the second portion of the material remains untreated after the anisotropic treatment. After increasing the etch selectivity, the first portion of the material is etched. The etching may be a wet or dry etch, and may further be isotropic or anisotropic. |

Semiconductor device and method for supporting ultra-thin semiconductor die
A first semiconductor substrate contains a first semiconductor material, such as silicon. A second semiconductor substrate containing a second semiconductor material, such as gallium nitride or aluminum gallium nitride, is formed on the first semiconductor substrate. The first semiconductor substrate and second semiconductor substrate are singulated to provide a semiconductor die including a portion of the second semiconductor material supported by a portion of the first semiconductor material. The semiconductor die is disposed over a die attach area of an interconnect structure. The interconnect structure has a conductive layer and optional active region. An underfill material is deposited between the semiconductor die and die attach area of the interconnect structure. The first semiconductor material is removed from the semiconductor die and the interconnect structure is singulated to separate the semiconductor die. The first semiconductor material can be removed post interconnect structure singulation. |
