Claim:
1. A semiconductor device, comprising: a first inductor; a patterned ground shielding (PGS) underlying the first inductor, the PGS comprising a first portion and a second portion; a first switch for electrically coupling the first portion of the PGS to the second portion of the PGS, wherein the first switch underlies the PGS and the first portion of the PGS is electrically coupled to the second portion of the PGS when the first switch is in a first state; a conductive element coupling the first switch to the first portion of the PGS, wherein the conductive element is situated between the PGS and the first switch; a glue oxide layer underlying the first switch; a first dielectric layer underlying the glue oxide layer; and a second inductor underlying the first dielectric layer.
