Abstract

Nitride semiconductor devices and methods of producing same are provided. The present invention includes forming a nitride semiconductor layer on a base body of the nitride semiconductor under selective and controlled crystal growth conditions. For example, the crystal growth rate, the supply of crystal growth source material and/or the crystal growth area can be varied over time, thus resulting in a nitride semiconductor device with enhanced properties.
