Abstract
A high electron mobility transistor (HEMT) includes a substrate, an HEMT stack spaced apart from the substrate, and a pseudo-insulation layer (PIL) disposed between the substrate and the HEMT stack. The PIL layer includes at least two materials having different phases. The PIL layer defines an empty space that is wider at an intermediate portion than at an entrance of the empty space.
