摘要:
An SOI semiconductor and method for making the same includes a substrate and dielectric support structures that support a silicon body above the substrate. This creates a void underneath the silicon body and thereby reduces the capacitance between the source/drain regions on body and the substrate.

A fully depleted silicon on insulator (SOI) field effect transistor (FET) includes a gate positioned above a channel region and an aligned back gate positioned below the channel region and the buried oxide later. Alignment of the back gate with the gate is achieved utilizing a disposable gate process and retrograde doping of the backgate.
