1. A 3D semiconductor device, the device comprising:
a first level comprising a first single crystal layer, said first level comprising first transistors,
wherein each of said first transistors comprises a single crystal channel;
first metal layers interconnecting at least said first transistors;
a second metal layer overlaying said first metal layers;
a first oxide layer disposed over said second metal layer;
a second oxide layer disposed over said first oxide layer; and
a second level comprising a second single crystal layer, said second level comprising second transistors,
wherein said second level overlays said first level,
wherein at least one of said second transistors comprises a raised source or raised drain transistor structure,
wherein said second level is directly bonded to said first level, and
wherein said bonded comprises direct oxide-to-oxide bonds.
