摘要：

We propose a universal MEMS technology platform for fabricating integrable passive components for radio frequency (RF) integrated circuits. This platform is based on a novel surface-micromachined Micro-Elevator by Self-Assembly (MESA) technique. Both high-Q inductors and variable capacitors can be realized by the MESA technology. A surface-micromachined spiral inductor that is raised by 250 mu m above the Si substrate has been experimentally demonstrated. The suspended inductor has less parasitic capacitance and substrate loss, and higher quality (Q) value and resonant frequency. The inductance of a 12.5-turn inductor is measured to be 24 nH. The results show that the self-assembled passive RF elements are suitable for monolithic integration.
