Abstract

Various embodiments of the present disclosure are directed towards an integrated chip a first undoped layer overlies a substrate. A first barrier layer overlies the first undoped layer and has a first thickness. A first doped layer overlies the first barrier layer and is disposed laterally within an n-channel device region of the substrate. A second barrier layer overlies the first barrier layer and is disposed within a p-channel device region that is laterally adjacent to the n-channel device region. The second barrier layer has a second thickness that is greater than the first thickness. A second undoped layer overlies the second barrier layer. A second doped layer overlies the second undoped layer. The second undoped layer and the second doped layer are disposed within the p-channel device region.
