Claim Text:
1. An apparatus comprising: a layer of glass, quartz or sapphire; a first silicon-on-insulator (SOI) structure comprising a first insulating layer and at least one first circuit layer formed on a first side of the first insulating layer, the first SOI structure being bonded to the layer of glass, quartz or sapphire such that the at least one first circuit layer is located between the first insulating layer and the layer of glass, quartz or sapphire, wherein the first insulating layer comprises a second side opposite the first side of the first insulating layer; an adhesive layer disposed between the layer of glass, quartz or sapphire and the first SOI structure such that the at least one first circuit layer of the first SOI structure is bonded directly to the layer of glass, quartz or sapphire using the adhesive layer; and a second SOI structure comprising a second insulating layer and at least one second circuit layer, wherein the second insulating layer comprises a first side and a second side, the first side of the second insulating layer facing the second side of the first insulating layer and the second side of the second insulating layer is opposite the first side of the second insulating layer, wherein the at least one second circuit layer comprises at least one first passive circuit element formed on and in direct contact with the first side of the second insulating layer and at least one second passive circuit element formed on and in direct contact with the second side of the second insulating layer, the second SOI structure being bonded to the first insulating layer such that the at least one first passive circuit element is located between the second insulating layer and the first insulating layer, wherein the second side of the first insulating layer is bonded to the at least one second circuit layer.
