摘要:
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 wafer level package having a pressure sensor and a fabrication method thereof are provided. A wafer having the pressure sensor is bonded to a lid, and electrical connecting pads are formed on the wafer. After the lid is cut, wire-bonding and packaging processes are performed. Ends of bonding wires are exposed and serve as an electrical connecting path. A bottom opening is formed on a bottom surface of the wafer, in order to form a pressure sensor path.

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.

A cooling coolant pipe of a server cabinet includes multiple tube bodies interconnected in series and at least one adjustable valve. In each of the tube bodies a first chamber and a second chamber that are adjacent to and separated from each other, the second chambers of the two adjacent tube bodies are in communication with each other, and a wall surface of each of the tube bodies has at least one connection port in communication with the first chamber. The adjustable valve is disposed in one of the tube bodies. The first chamber in each of the tube bodies is in communication with the second chamber in the tube body through the adjustable valve. In this way, the adjustable valve adjusts the flow rate of a cooling fluid flowing from the second chamber to the first chamber.

The mechanisms of forming an interconnect structures described above involves using a reflowed conductive layer. The reflowed conductive layer is thicker in smaller openings than in wider openings. The mechanisms may further involve forming a metal cap layer over the reflow conductive layer, in some embodiments. The interconnect structures formed by the mechanisms described have better electrical and reliability performance.

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.

A modulized heat-dissipation control method for a datacenter is provided. In this method, a temperature sensor is used to sense inner temperatures of multiple servers and CPU temperatures in the multiple servers. If any one of the CPU temperatures is abnormal, a flow of a first coolant is adjusted. If any one of the inner temperatures is abnormal, a rotating speed of a fan module is adjusted. If the rotating speed of the fan module has reached its maximum, a flow of a second coolant is adjusted.
