Abstract
Vertical gate all around devices are formed by initially forming a first doped region and a second doped region that are planar with each other. A channel layer is formed over the first doped region and the second doped region, and a third doped region is formed over the channel layer. A fourth doped region is formed to be planar with the third doped region, and the first doped region, the second doped region, the third doped region, the fourth doped region, and the channel layer are patterned to form a first nanowire and a second nanowire, which are then used to form the vertical gate all around devices.
