Abstract
One illustrative method disclosed herein includes, among other things, forming a vertically oriented channel semiconductor structure, forming a layer of a bottom spacer material around the vertically oriented channel semiconductor structure and forming a sacrificial material layer above the layer of a bottom spacer material. In this example, the method further includes forming a sidewall spacer adjacent the vertically oriented channel semiconductor structure and above an upper surface of the sacrificial material layer, removing the sacrificial material layer so as to define a replacement gate cavity between a bottom surface of the sidewall spacer and the layer of a bottom spacer material, and forming a replacement gate structure in the replacement gate cavity.
