Abstract:
Methods of locally changing the BOX layer of a MOSFET device to a high-k layer to provide different Vts with one backside voltage and the resulting device are provided. Embodiments include providing a Si substrate having a BOX layer formed over the substrate and a SOI layer formed over the BOX layer; implanting a high current of dopants into at least one portion of the BOX layer; performing a high-temperature anneal of the BOX layer; forming first and second fully depleted silicon-on-insulator (FDSOI) transistors on the SOI layer, the first FDSOI transistors formed above either the BOX layer or the at least one portion of the BOX layer and the second FDSOI transistors formed above the at least one portion of the BOX layer; and applying a single voltage across a backside of the Si substrate.

Claim (Index 5):
A device comprising:\n a silicon (Si) substrate having a buried oxide (BOX) layer formed over the substrate and a silicon-on-insulator (SOI) layer formed over the BOX layer; high current of dopants implanted into at least one portion of the BOX layer; first and second fully depleted silicon-on-insulator (FDSOI) transistors formed on the SOI layer, wherein the BOX layer below the first FDSOI transistors is either implanted with a first dopant, forming a high-k layer, or is non-implanted, and the BOX layer below the second FDSOI transistors is implanted with a second dopant, forming a high-k layer, the first and second dopants being different; and a backgate region formed on a bottom surface of the Si substrate, wherein the second dopant comprises hafnium (Hf), zirconium (Zr), titanium (Ti), or tantalum (Ta).
