    Abstract: A semiconductor device structure is provided. The semiconductor device has a first dielectric wall between an n-type source/drain region and a p-type source/drain region to physically and electrically isolate the n-type source/drain region and the p-type source/drain region from each other. A second dielectric wall is formed between a first channel region connected to the n-type source/drain region and a second channel region connected to the p-type source/drain region. A contact is formed to physically and electrically connect the n-type source/drain region with the p-type source/drain region, wherein the contact extends over the first dielectric wall. The first electric wall has a gradually decreasing width W5 towards a tip of the dielectric wall from a top contact position between the first dielectric wall and either the n-type source/drain region or the p-type source/drain region.
