This paper demonstrates a W-band monolithic Low no ise amplifier which is based on UMS company0.1μm GaAs pHEMT process. The circuit is designed with three-stages amplifiers to meet higher power *** size is only 1×1.7mm yet. The measured results of LNA show the power gain of 12 dB, low NF of 4.7dB,which are consistent well with the simulation ones.
As the semiconductor industry advances to nano-technology points, Network on Chip (NoC) components are becoming vulnerable to errors during the system operation. Consequently, fault-tolerant techniques for NoC are nee...

The mechanism of Al-enhanced etching of silicon by reactive ions in SF6/O2 environment was studied by experiment and statistical analysis. The results indicate that the Al-enhanced etching of silicon in SF6/O2 environment is little affected by other etching conditions. Simultaneously, the results also indicate that the enhancement effect of Al on etching rate of silicon does not result from the rise of the substrate temperature, but it mainly results from catalytic action of an AlF monolayer formed by Al, which A1F promotes decomposition of SF6 to produce more F radicals.

This work reports a valveless piezoelectric micropump with high pressure load and high flowrate. The experimental results showed that the maximum displacement of the actuator and the output flowrate of the micropump could reach 18.4 μm and 308 mL/min under zero pressure load, respectively, which was highly consistent with the numerical analysis. The maximum output pressure reached 47 kPa, and the pump was extremely stable under various temperatures from room temperature to 80°C, with frequency variations of only −150 Hz. The micropump demonstrated its great potential for wearable/portable application, especially for blood pressure monitoring.

A calculation model of the thermal stresses in a microstructure fabricated by multilayer thin films was established depending on the processing steps and it was verified by Stoney's equation under the same conditions. Furthermore, it was applied to calculate the deformation of a micro-cantilever fabricated by multilayer thin films under residual stresses. The calculated results were compared with the experimental results to show that their difference is less than 10%. Therefore, the model is applicable and can provide a theory foundation for designing and optimizing of the microstructure fabricated by multilayer films.
