摘要： When using hot alkaline etchants such as KOH, the wafer front side, where various devices and/or circuits are located, must be isolated from any contact with the etchant. This has been achieved by using two chambers that are separated from each other by the wafer that is to be etched. Etching solution in one chamber is in contact with the wafer's back surface while deionized water in the other chamber contacts the front surface. The relative liquid pressures in the chambers is arranged to be slightly higher in the chamber of the front surface so that leakage of etchant through a pin hole from back surface to front surface does not occur. As a further precaution, a monitor to detect the etchant is located in the DI water so that, if need be, etching can be terminated before irreparable damage is done.

摘要： Methods and apparatus operating in a stream processing network perform load shedding and dynamic resource allocation so as to meet a pre-determined utility criterion. Load shedding is envisioned as an admission control problem encompassing source nodes admitting workflows into the stream processing network. A primal-dual approach is used to decompose the admission control and resource allocation problems. The admission control operates as a push-and-pull process with sources pushing workflows into the stream processing network and sinks pulling processed workflows from the network. A virtual queue is maintained at each node to account for both queue backlogs and credits from sinks. Nodes of the stream processing network maintain shadow prices for each of the workflows and share congestion information with neighbor nodes. At each node, resources are devoted to the workflow with the maximum product of downstream pressure and processing rate, where the downstream pressure is defined as the backlog difference between neighbor nodes. The primal-dual controller iteratively adjusts the admission rates and resource allocation using local congestion feedback. The iterative controlling procedure further uses an interior-point method to improve the speed of convergence towards optimal admission and allocation decisions.

摘要： In a method for visualizing query results in stream processing systems, a visualization service receives a query from a client to visualize data in a stream processing application. The query is sent from the visualization service to a query-able operator of the stream processing application. At the query-able operator, an operation is performed using history data in the query-able operator to produce a first result that satisfies the query and the first result is sent to the visualization service. At the query-able operator, another operation is performed using new data received by the query-able operator to produce a second result that satisfies the query and the second result is sent to the visualization service. The first and second results are output from the visualization service to the client.

摘要： In the prior art LDMOSFET devices capable of handling high power have been made by locating the source contact on the bottom surface of the device, allowing for good heat sinking, with connection to the source region being made through a sinker. However, this structure has poor high frequency characteristics. Also in the prior art, good high frequency performance has been achieved by introducing a dielectric layer immediately below the source/drain regions (SOI) but this structure has poor power handling capabilities. The present invention achieves both good high frequency behavior as well as good power capability in the same device. Instead of inserting a dielectric layer over the entire cross-section of the device, the dielectric layer is limited to being below the heavily doped section of the drain with a small amount of overlap into the lightly doped section. The structure is described in detail together with a process for manufacturing it.

摘要： An inductor has a spiral aluminum track deposited on an oxide layer over a silicon substrate. The substrate is etched away to form a trench, which extends around beneath the track and provides an air gap having a low dielectric constant. The oxide layer has an inner region within the track, an outer region outside the track and a bridging region extending between the other regions. The bridging region is comprised of intact bridges and gaps therebetween, which are open to the trench and through which an etchant has access to the silicon substrate to form the trench by etching.
