Abstract:
1. A method for fabricating a compound nitride structure, comprising: depositing a first layer over one or more substrates in a processing chamber using a first group-III precursor comprising a first group-III element and a first nitrogen containing precursor, wherein the first layer comprises nitrogen and the first group-III element; removing the one or more substrates from the processing chamber after depositing the first layer without exposing the one or more substrates to atmosphere; flowing a first cleaning gas into the processing chamber after removing the one or more substrates from the processing chamber to remove at least a portion of the first layer disposed on a surface of the processing chamber; transferring the one or more substrates into the processing chamber without exposing the one or more substrates to atmosphere after removing at least a portion of the first layer; and depositing a second layer over the first layer in the processing chamber using a second group-III precursor and a second nitrogen containing precursor, wherein the second group-III precursor comprises a second group-III element not comprised by the first group-III precursor.
