Abstract
A sensing device includes a substrate having a source region and a drain region formed therein. A gate structure is formed over the substrate and includes a gate dielectric and a gate conductor. The gate conductor is formed on the gate dielectric and disposed between the source region and the drain region. A dielectric layer is formed over the substrate and has a depth configured to form a well over the gate conductor. A gate extension is formed in contact with or as part of the gate conductor and including a conductive material covering one or more surfaces of the well.
