Abstract
A transistor is positioned on a substrate. The transistor includes a semiconductor layer. A buffer layer is positioned between the substrate and the semiconductor layer of the transistor, including an insulating material. A bottom layer is positioned between the substrate and the buffer layer. The bottom layer and the semiconductor layer overlap each other. The bottom layer includes a first layer, a second layer, and a third layer that are stacked on each other in a direction away from the substrate.
