Abstract

An integrated circuit includes multiple active layers. Preferably, a semiconductor-on-insulator (SOI) or silicon-on-insulator wafer is utilized to house a first active layer. A second active layer is provided above an insulative layer above the SOI substrate. Solid phase epitaxy can be used to form the second active layer. Subsequent active layers can be added by a similar technique. A seeding window can also be utilized.
