| Abstract: | It is introduced a new kind of method of inductor fabrication, whose internal down-lead adopts ohm contact formed by the boron heavily dosed region and the Au evaporated. And the authours put forward a program to increase Q-factors, that is to dig holes on the back of silicon by laser for further reducing substrate. The relations of geometry parameter versus Magnetic Flux Density and inductance are analyzed by Ansys soft on the bases of the prevalent mold of inductor. As conclusion shows, this method has the advantages of simple technology, compatible of CMOS technology, and has extensive future. |
