Abstract: A semiconductor structure includes an upper device stacked over a lower device. In an example, the upper device includes (i) a first source region, (ii) a first drain region, (iii) a body of semiconductor material extending laterally from the first source region to the first drain region, and (iv) a first gate structure at least in part wrapped around the body. In an example, the lower device includes (i) a second source region, (ii) a second drain region, and (iii) a second gate structure at least in part laterally between the second source region and the second drain region. In an example, the lower device lacks a body of semiconductor material extending laterally from the second source region to the second drain region. In another example, the upper device lacks a body of semiconductor material extending laterally from the first source region to the first drain region.
