    • An ultra-wide bandwidth multi-channel offset Cassegrain dichroic antenna system serves for bidirectional signal transmission between a ground-based system and at least one satellite. By properly selecting the high and low frequency band, ultra wide bandwidths for both high and low frequency band signals are provided. The band widths are about 15%, even up-to 50%, of the carrier frequency. Especially, the band widths for high frequency band signals are much wider than that for low frequency band signals. The low frequency band can be from 10.7 up-to 12.75 GHz while the high frequency band can be from 17 up-to 30 GHz. Furthermore, in order to achieve ultra-wide bandwidth, a surface of a dichroic sub-dish is divided into a plurality of unit areas. Arrangements of the metal dichroic element of one unit area are slightly different from another unit area f, while the metal elements on same unit area are identical.

    • The present disclosure relates to a semiconductor body etching apparatus having a multi-zone end point detection system. In some embodiments, the multi-zone end point detection system has a processing chamber that houses a workpiece that is etched according to an etching process. A plurality of end point detector (EPD) probes are located within the processing chamber. Respective EPD probes are located within different zones in the processing chamber, thereby enabling the detection of end point signals from multiple zones within the processing chamber. The detected end point signals are provided from the plurality of EPD probes to an advanced process control (APC) unit. The APC unit is configured to make a tuning knob adjustment to etching process parameters based upon the detected end point signals and to thereby account for etching non-uniformities.

    • A server rack heat dissipation system for a server including an electronic component comprises a first and a second heat dissipation assembly. The first heat dissipation assembly includes a first heat exchanger and a first pipeline. The first heat exchanger is inside the server rack and in thermal contact with the electronic component. The first pipeline is in thermal contact with the first heat exchanger and has a first coolant. The second heat dissipation assembly includes a second heat exchanger. The second heat exchanger is inside the server rack and in thermal contact with the first pipeline. The second heat exchanger can remove the heat of the electronic component in the first coolant in advance. Accordingly, the time of the first coolant being maintained in a vapor phase can be shortened, so that a power the fluid driving device used for driving the first coolant is reduced.
