Abstract:
1. A method of fabricating a compound nitride semiconductor structure, the method comprising: flowing a first group-III precursor and a first nitrogen precursor into a first processing chamber, the first group-III precursor comprising a first group-III element; depositing a first layer over a first side of the substrate with a thermal chemical-vapor-deposition process at an elevated temperature within the first processing chamber using the first group-III precursor and the first nitrogen precursor, the first layer comprising nitrogen and the first group-III element; depositing a second layer over a second side of the substrate opposite the first side with a thermal chemical-vapor-deposition process within the first processing chamber using the first group-III precursor and the first nitrogen precursor, the second layer comprising nitrogen and the first group-III element; and cooling the substrate after depositing the first and second layers without substantially deforming a shape of the substrate.
