Abstract
A semiconductor including a first sacrificial layer located directly between a first substrate layer and a second substrate layer, where the first sacrificial layer has a first thickness. The second substrate layer has a second thickness and where the second thickness is larger than the first thickness. A source/drain located on top of the second substrate layer and a dielectric landing pad located within the first sacrificial layer. A frontside contact comprised of a first section and a second section. The first section of the frontside contact is located on top of the source/drain. The second section of the frontside contact is a via that extends downwards past and through the dielectric landing pad.
