Abstract
A transistor structure includes a first channel layer over a second channel layer, where the first and the second channel layers include monocrystalline silicon. An epitaxial source material is coupled to a first end of the first and second channel layers. An epitaxial drain material is coupled to a second end of the first and second channel layers, a gate electrode is between the epitaxial source material and the epitaxial drain material, and around the first channel layer and around the second channel layer. The transistor structure further includes a first gate dielectric layer between the gate electrode and each of the first channel layer and the second channel layer, where the first gate dielectric layer has a first dielectric constant. A second gate dielectric layer is between the first gate dielectric layer and the gate electrode, where the second gate dielectric layer has a second dielectric constant.
