摘要： A power control system and method for communication system using space-time transmit diversity scheme. In the power control method, transmission power information of a plurality of antennas or a plurality of subcarriers is monitored. A new space-time code is generated by concatenating the monitored transmission power information and symbols to be transmitted. Symbols encoded using the generated space-time code are generated and the encoded symbols are transmitted. Accordingly, after determining the transmission power of each antenna, the transmission power information is monitored so that the transmission power information that does not experience the channel gain can be used at a next slot. Therefore, the performance degradation due to the round trip time can be reduced, thereby improving the system capacity and performance.

摘要： In a semiconductor device package having a stress relief spacer, and a manufacturing method thereof, metal interconnect fingers extend from the body of a chip provide for chip interconnection. The metal fingers are isolated from the body of the chip by a stress-relief spacer. In one example, such isolation takes the form of an air gap. In another example, such isolation takes the form of an elastomer material. In either case, mismatch in coefficient of thermal expansion between the metal interconnect fingers and the body of the chip is avoided, alleviating the problems associated with cracking and delamination, and leading to improved device yield and device reliability.

摘要： Provided are semiconductor device packages and methods for fabricating the same. In some embodiments, the method includes providing a semiconductor chip on a substrate with through electrodes formed in the substrate, and providing a capping layer on the substrate to receive the semiconductor chip in a recess formed in the capping layer. The capping layer is coupled to the substrate by a bonding layer formed on the substrate, and the capping layer covers the semiconductor chip provided on the substrate. The processing of the substrate and the capping layer can be separately performed, thus allowing the material for the capping layer and/or the substrate to be selected to reduce (e.g., to minimize) a difference between the thermal expansion coefficients of the capping layer material and the substrate material.
