Abstract. This paper presents fabrication results and RF characterization
and modeling of highperformance thick copper / polyimide inductors.
Quality factors in excess of 15 and resonant frequencies in excess of 10
GHz were demonstrated using 5-μm-thick copper layers on top of
highresistivity silicon wafers, a performance that cannot be obtained
using other conventional fabrication technologies. |
