Abstract :
Microwave characteristics of spiral inductors on low-resistivity Si substrates have been improved by implanting Si28+ ions. Spiral inductors fabricated on these implanted substrates demonstrate better Q-value and microwave performance. The Q-value of inductor enhanced 60% on the implanted substrates than that of low resistivity Si substrates. An equivalent circuit model of inductor has been evaluated to discuss the effect of substrate loss
