Abstract:
A field effect transistor (FET) with an underlying airgap and methods of manufacture are disclosed. The method includes forming an amorphous layer at a predetermined depth of a substrate. The method further includes forming an airgap in the substrate under the amorphous layer. The method further includes forming a completely isolated transistor in an active region of the substrate, above the amorphous layer and the airgap.

Claim (Index 8):
A structure, comprising:\n at least one deep trench structure in a bulk substrate, on sides of an active region; sidewall structures on sidewalls of the at least one deep trench structure; and a lateral undercut in the bulk substrate starting at a bottom of the at least one deep trench structure; wherein the at least one deep trench structure is completely with material to isolate the lateral undercut as an airgap in the bulk substrate under the active region, wherein the material is formed directly on the sidewall structures.
