衬底结构特征对硅基螺旋电感性能的影响

使用三维电磁场模拟的方法对不同硅衬底结构螺旋电感进行了模拟和分析.通过改变衬底的电导率、隔离层的厚度以及隔离层的材料、衬底引入硅锗合金层等模拟,分析了电感性能的变化.结果表明随着电导率的减小,电感的性能会增强,但改善的幅度会逐渐减小.厚的SiO2隔离层有利于减小衬底损耗,但是会给工艺增加难度.采用低k材料作为隔离层是改善电感性能的一种比较理想的方法.

Guiding of 150 keV O6+ ions through nanocapillaries in an uncoated Al2O3 membrane: special time dependence of the transmission profile width

This paper reports that the transmission of O6+ ions with energy of 150keV through capillaries in an uncoated Al2O3 membrane was measured, and agreements with previously reported results in general angular distribution of the transmitted ions and the transmission fractions as a function of the tilt angle well fitted to Gaussian-like functions were observed. Due to using an uncoated capillary membrane, our c is larger than that using a gold-coated one with a smaller value of E-p/q, which suggests a larger equilibrium charge Q(infinity) in our experiment. The observed special width variation with time and a larger width than that using a smaller E-p/q were qualitatively explained by using mean-field classical transport theory based on a classical-trajectory Monte Carlo simulation.
