Claim 9:
10. The semiconductor device of claim 9, further comprising:
a first vertical gate structure including a first metal-containing layer that extends in the vertical direction while being coupled to the first horizontal gate structure on the second side of the first stacked structure; and
a second vertical gate structure including a second metal-containing layer that extends in the vertical direction while being coupled to the second horizontal gate structure on the second side of the second stacked structure,
wherein the first gate electrode layer further extends to surround side and lower surfaces of the first metal-containing layer,
the first gate dielectric layer further extends to surround side and lower surfaces of the further extended first gate electrode layer,
the second gate electrode layer further extends to surround side and lower surfaces of the second metal-containing layer, and
the second gate dielectric layer further extends to surround side and lower surfaces of the further extended second gate electrode layer.
