Abstract
A semiconductor device includes a substrate, a stack structure and a transistor. The substrate includes a first region and a second region. The stack structure is formed over the substrate in the first region. The transistor structure has a gate formed in the second region. A bottom portion of the gate structure is disposed at a height from the substrate that is less than a height between the substrate and a bottom portion of the stack structure.
