High Q copper inductors were fabricated on low-cost and low-loss BT and glass substrate using electroplating process. A differential LC VCO circuit was designed using these high Q inductors at 2.4GHz. Flip chip and MCM technology were applied to assemble the active chips on BT and glass substrate. The inductors exhibited Q-factor as high as 30 at 2.4GHz. VCOs with copper inductors on BT and glass substrate had phase noise of -108 dBc/Hz at 600 kHz offset for a 2.4GHz carrier, which is 6dB improvement compared with the one with on-chip Al inductors.
