Abstract:
High breakdown voltage devices are provided. In one aspect, a method of forming a device having a VTFET and a LDVTFET includes: forming a LDD in an LDVTFET region; patterning fin(s) in a VTFET region to a depth D1; patterning fin(s) in the LDVTFET region, through the LDD, to a depth D2>D1; forming bottom source/drains at a base of the VTFET/LDVTFET fins; burying the VTFET/LDVTFET fins in a gap fill dielectric; recessing the gap fill dielectric to full expose the VTFET fin(s) and partially expose the LDVTFET fin(s); forming bottom spacers directly on the bottom source/drains in the VTFET region and directly on the gap fill dielectric in the LDVTFET region; forming gates alongside the VTFET/LDVTFET fins; forming top spacers above the gates; and forming top source/drains above the top spacers. A one-step fin etch and devices having VTFET and long channel VTFETs are also provided.

Claim (Index 7):
The method of  claim 6 , wherein the dopant concentration c1 is from about 1\u00d710 17  atoms/cm 3  to about 1\u00d710 18  atoms/cm 3 , and ranges therebetween, and wherein the dopant concentration c2 is from about 1\u00d710 15  atoms/cm 3  to about 1\u00d710 16  atoms/cm 3 , and ranges therebetween.
