Abstract
A semiconductor device is provided. The semiconductor device includes a first field effect transistor (FET) region, a second FET region and a backside signal distribution network (BSSDN). The first FET region includes a substrate, interlayer dielectric (ILD), shallow trench isolation (STI) disposed in the substrate and a contact that extends through the STI and the ILD. The second FET region includes a substrate, interlayer dielectric (ILD), shallow trench isolation (STI) disposed in the substrate and a contact that extends to the STI. The BSSDN is disposed on the ILD in the first and second regions to contact with the contact in the first FET region.
