Claim:
1. A multilayer semiconductor device structure having different circuit functions on different semiconductor device layers, the semiconductor structure comprising: a first semiconductor device layer fabricated on a bulk substrate, the first semiconductor device layer comprising a first semiconductor device for performing a first circuit function, the first semiconductor device layer including a patterned top surface of a gate material and a dielectric material; a second semiconductor device layer fabricated on a second channel material above a buried oxide of a semiconductor-on-insulator (“SOI”) substrate, the second semiconductor device layer comprising a second semiconductor device for performing a second circuit function, wherein the second circuit function is different from the first circuit function; and an adhesive layer of glue, wherein a bottom surface of the buried oxide of the SOI substrate is bonded to the patterned top surface of the first semiconductor device layer via the adhesive layer and wherein the buried oxide of the SOI substrate electrically insulates the second channel material from the first semiconductor device, and wherein the second semiconductor device layer includes:
