A semiconductor structure includes a first dielectric layer having a k value of less than about 2.7, a second dielectric layer over the first dielectric layer, a via in the first dielectric layer, a conductive line in the second dielectric layer, wherein the conductive line extends from a top surface of the second dielectric layer into the second dielectric layer and electrically coupled to the via, a third dielectric layer on the second dielectric layer, and a fourth dielectric layer between the second dielectric layer and the conductive line. The second dielectric layer is preferably a porous material and has an ultra low k value. The k value of the second dielectric layer is lower than the k values of the first, the third and the fourth dielectric layers.

Methods, systems, and computer program products for implementing automatic protection switching for media packets, such as ATM cells or IP packets that carry media content, in a device that includes an Ethernet switching fabric are disclosed. According to one method, first and second packet network interfaces of the device are configured to function as working and protection APS interfaces. At least one of a media processing resource and an Ethernet switch fabric of the device are configured to replicate egress media packets from the media processing resource to the working and protection APS interfaces. Egress media packets from the media processing resource are forwarded to the working and protection APS interfaces via the switch fabric. Ingress media packets received at the working APS interface are forwarded to the media processing resource via the Ethernet switch fabric. Media packets received at the protection APS interface are discarded.

Methods and systems for classifying incoming and/or outgoing packets to sessions in a media gateway store session identifiers for active sessions in a media gateway in a memory. Each session identifier is a combination of a local network address, a local port number, a remote network address, and a remote port number for the session. Alternatively, each session identifier is a combination of a local network address and a local port number. An incoming and/or outgoing packet is classified to one of the active sessions by using network address and port number information from the packet to perform a lookup for a corresponding session identifier in the memory.
摘要:
An apparatus that includes a packet data ingress, a packet data egress, and a packet data switching matrix configured to switch packet data from the packet data ingress to the packet data egress. The apparatus may further include a packet data jitter buffer and a packet data splitter, wherein the packet data splitter interposes the packet data ingress and the packet data switching matrix and is configured to multicast the packet data to the packet data switching matrix and the jitter buffer.
摘要:
An apparatus including a plurality of packet processors each included in one of a plurality of voice-over-internet-protocol (VoIP) network interfaces. Each of the plurality of packet processors is configured to cache a latest version of realtime transport control protocol (RTCP) report data by discarding an older version of the RTCP report data. The RTCP report data includes at least one of RTCP sender report data and RTCP receiver report data. The apparatus also includes a packet data switching matrix configured to switch packet data between ones of the plurality of VoIP network interfaces. A central processor of the apparatus is configured to generate a final session detail record upon the termination of a VoIP-session by selecting RTCP session-concluding report data from a plurality of RTCP final report data each cached by a corresponding one of the plurality of packet processors.
摘要:
A megasonic immersion lithography exposure apparatus and method for substantially eliminating microbubbles from an exposure liquid in immersion lithography is disclosed. The apparatus includes an optical system for projecting light through a mask and onto a wafer. An optical transfer chamber is provided adjacent to the optical system for containing an exposure liquid. At least one megasonic plate operably engages the optical transfer chamber for inducing sonic waves in and eliminating microbubbles from the exposure liquid.
摘要:
A system and method for automatically determining the shipping weight and cost of a plurality of photofinishing items from a service provider without physically weighing the photofinishing order. A computer system receives photofinishing orders from the customers and associates an order ID with respect to each of the photofinishing orders. The orders are filled and sent to a packing station for assembling the photofinishing order. Each order is placed in a shipping package having the order ID thereon in a machine readable format. A reading device reads order ID and obtains information for determining the associated estimated weight for each package. A printer produces a manifest to be used in shipping the plurality of photofinishing orders wherein the manifest provides the estimated weight and cost for each of the orders that is given to the shipping agent for shipment to customers.
