Patent ID: 7084462

Claim:
A semiconductor device structure comprising: a unitary single-crystal semiconductor region of a substrate, the unitary single-crystal semiconductor region having an exposed horizontally extending major surface; a first field effect transistor (“FET”) having a first source region and a first drain region, the first source region and first drain region occupying a first source portion and a first drain portion, respectively, of the unitary single-crystal semiconductor region extending from the major surface, the first source region and the first drain region defining a first source-drain conduction path; at least one second field effect transistor (“FET”) having a second source-drain conduction path electrically in parallel with the first source-drain conduction path of the first FET, the at least one second FET having a second diffusion region occupying a second portion of the unitary single-crystal semiconductor region extending from the major surface, the second diffusion region including at least one of a second source region and a second drain region, the second source-drain conduction path extending between the second diffusion region and at least one of the first source region and the first drain region; and a body contact region occupying a third portion of the unitary single-crystal semiconductor region extending from the major surface, the body contact region having a junction with the second diffusion region.
