Patent ID: 7374960

Claim:
A method of fabricating a compound nitride semiconductor structure, the method comprising: disposing a substrate within a first processing chamber; flowing a first group-III precursor and a first nitrogen precursor into the first processing chamber, the first group-III precursor comprising a first group-III element; depositing a first layer over the substrate with a thermal chemical-vapor-deposition process 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; transferring the substrate from the first processing chamber to a transfer chamber different from the first processing chamber; measuring a temperature of the first layer within the transfer chamber; measuring a curvature of the first layer within the transfer chamber; transferring the substrate to a second processing chamber different from the first processing chamber and different from the transfer chamber; and depositing a second layer over the first layer within the second processing chamber.
