Claim 0:
1. A semiconductor device, comprising:
a base;
a first field effect transistor, wherein the first field effect transistor is disposed on a first side of the base, and wherein the first field effect transistor includes:
a first channel portion;
a second channel portion, wherein the first channel portion is disposed between the second channel portion and the base; and

a first insulation layer, wherein the first insulation layer is disposed between the first channel portion and the base;
a second field effect transistor, wherein the second field effect transistor is disposed on the first side of the base, and wherein the second field effect transistor includes:
a channel forming layer;
a gate insulation layer, wherein at least a portion of the gate insulation layer is between the channel forming layer and the base;
a gate electrode, wherein at least a portion of the gate electrode is between the gate insulation layer and the base; and
a second insulation layer,

wherein the second insulation layer is between the gate electrode and the base, and
wherein a thickness of the second insulation layer is larger than a thickness of the first insulation layer.
