Abstract
A semiconductor device comprises a first conductive structure extending along a vertical direction and a second conductive structuring extending along the vertical direction. The second conductive structure is spaced apart from the first conductive structure along a lateral direction. The semiconductor device further comprises a plurality of third conductive structures each extending along the lateral direction. The plurality of third conductive structures are disposed across the first and second conductive structures. The semiconductor device further comprises a first semiconductor channel extending along the vertical direction. The first semiconductor channel is disposed between the plurality of third conductive structures and the first conductive structure and between the plurality of third conductive structures and the second conductive structure. The first and second conductive structures each have a varying width along the lateral direction, and the first semiconductor channel has a doping concentration varying along the vertical direction.
