This work gives an overview of the different developments for silicon germanium (Si1−xGex) from a MEMS post-processing perspective. First, the maximum processing temperature that does not introduce any damage or degradation into the standard characteristics of the CMOS driving electronics is specified. Then, the optimal type of silicon and germanium gas sources and deposition technique that results in an economical process are identified. Next, the selection criteria for a low thermal budget doping method and doping species are discussed. Finally, the advantage and disadvantage for the different approaches implemented for enhancing the physical properties of poly Si1−xGex at a CMOS backend compatible temperature are highlighted. It is shown that the optimal method depends on the application requirements and the CMOS technology used for realizing the driving electronics. 相似文献

Heat treatments adversely affect the functional properties of the egg white. The selected properties of egg white after in-shell pasteurization by microwave heating were compared to that of egg white after in-shell pasteurization by immersion in hot water. The effects of the heat treatments on egg white enthalpy of denaturation, viscosity, turbidity, foam density, and stability, and also the dielectric properties, were investigated and compared to that of untreated egg white. Results demonstrated that microwave pasteurized in-shell eggs had nearly 20% higher enthalpy of denaturation, 4 times more viscosity, 50% more stable foam with 30% less foam density and 78% clearer, on an average, when compared to the water bath pasteurized ones. 相似文献

运用多体系统理论和齐次坐标变换方法,以"S"形检测试件为对象,针对一种刀具双摆动五轴数控机床建立了运动学模型和几何误差模型。利用UG NX8.0进行了加工仿真和后置处理,将生成的数控代码代入所建立的运动学模型中,生成了理想情况下刀具在"S"形试件坐标系中的扫描轨迹;在"S"形试件的直纹面上选取了75个点,将每个点的点位数据代入几何误差模型中,得到"S"形试件直纹面上轮廓误差大小分布情况,将所得结果与通过三坐标测量机测量得到的结果进行对比,验证了几何误差模型具有比较理想的预测性能。 相似文献
