Abstract
An integrated enhancement/depletion mode high electron mobility transistor (HEMT) includes a substrate, a first buffer layer, a first barrier layer, a first channel layer, a first source, a first drain, a first gate, a second buffer layer, a second barrier layer, a second channel layer, a second source, a second drain, and a second gate. The first buffer layer is on the substrate. The first barrier layer is on a first area of the first buffer layer, the first channel layer is on the first barrier layer, and the first source, the first drain, and the first gate are on the first channel layer. The second buffer layer is on a second area of the first buffer layer, the second bather layer is on the second buffer layer, the second channel layer is on the second barrier layer, and the second source, the second drain, and the second gate are on the second channel layer.
