Provided is a transistor and a method for forming a transistor in a semiconductor device. The method includes performing at least one implantation operation in the transistor channel area, then forming a silicon carbide/silicon composite film over the implanted area prior to introducing further dopant impurities. A halo implantation operation with a very low tilt angle is used to form areas of high dopant concentration at edges of the transistor channel to alleviate short channel effects. The transistor structure so-formed includes a reduced dopant impurity concentration at the substrate interface with the gate dielectric and a peak concentration about 10-50 nm below the surface. The dopant profile also includes the transistor channel having high dopant impurity concentration areas at opposed ends of the transistor channel.

A MOSFET disposed between shallow trench isolation (STI) structures includes an epitaxial silicon layer formed over a substrate surface and extending over inwardly extending ledges of the STI structures. The gate width of the MOSFET is therefore the width of the epitaxial silicon layer and greater than the width of the original substrate surface between the STI structures. The epitaxial silicon layer is formed over the previously doped channel and is undoped upon deposition. A thermal activation operation may be used to drive dopant impurities into the transistor channel region occupied by the epitaxial silicon layer but the dopant concentration at the channel location where the epitaxial silicon layer intersects with the gate dielectric, is minimized.

Mass based methods and systems for estimating soot load in a filter of an after-treatment system for exhaust stream are provided. The after-treatment system can comprise a sensor, a filter, and a processor configured to estimate soot load in the filter based on a mass based multi-layer model. An example system includes a virtual sensor comprising an estimator for providing information corresponding to a filter outlet NO2 concentration. An example method includes the steps of providing the mass based multi-layer model, passing the exhaust stream through the filter, and using the sensor to monitor a condition of the exhaust stream. The example method further includes the steps of calculating a total regeneration rate based on the multi-layer model by solving a second-order ordinary differential equation with a plurality of parameters using an analytical approach, and estimating the soot load based on the calculated total regeneration rate.

Structures and methods to facilitate channel bundling are disclosed. In one embodiment, signal distribution circuitry includes a data path with at least two registers coupled to adjacent sets of data channels in a bundle of data channel sets. In another embodiment, self-switch circuits allow channels in a bundle of channel-sets to switch from bundle-wide signals to locally generated signals after the bundle-wide signals have been synchronously distributed to all channel sets in the bundle. In a particular embodiment, signal distribution circuitry is used to distribute a divided clock signal. In another particular embodiment, signal distribution circuitry is used to distribute enable signals for first-in first-out circuits (“FIFOs”) located in channels of each data channel set in a channel set bundle. In a particular aspect of an embodiment, FIFO read and write operations across a channel set bundle are initiated such that a difference between read and write pointer signals is the same in each channel set.

This invention provides consultative transfer service method and apparatus. The method comprises the following steps: firstly, user A establishes a call with user B, and then, user B establishes a call with user C and initiates a call transfer request of requesting to transfer its call with user A to user C; the application server of user B heads off the request and returns an accept response to user B; the application server of user B firstly initiates a call invitation to user C, acquires the media parameter information of user C, and instructs user C to replace the call user C and user B; the application server of user B initiates a call re-invitation to user A, provides the media parameter information of user C, instructs user A to carry out media switch, and acquires the media parameter information of user A; the application server of user B provides the media parameter information of user A to user C, and instructs user C to establish a media stream connection with user A; and user C releases its original call with user B.

A method for forming a vertical coupling structure for non-adjacent resonators is provided to have a first and a second resonators, a dielectric material layer, a first and a second high-frequency transmission lines and at least one via pole. The first and the second resonators respectively have a first and a second opposite metal surfaces. The dielectric material layer is disposed between the opposite second metal surfaces of the first and the second resonators. The first and the second transmission lines are respectively arranged at sides of the first metal surfaces of the first resonator and the second resonator. The first high-frequency transmission line is vertically connected to the second high-frequency transmission line by the via pole.
