Patent ID: 6984592

Claim:
A method of manufacturing a semiconductor structure, the method comprising: providing a semiconductor substrate or substrate assembly; providing at least one precursor compound of the formula M(keto) y (Formula I) and at least one precursor compound of the formula AlY 3 (Formula II), wherein: M is yttrium, scandium, or a lanthanide metal; each “keto” is independently a diketonate or ketoimine ligand; each Y group is independently R 1 or an amine of the formula (NR 2 R 3 ), wherein each R 1 , R 2 , and R 3 is independently hydrogen or an organic group; y is 0 to 5 and is dependent on the oxidation state of M; and contacting the precursor compounds to form a metal-doped aluminum oxide layer on one or more surfaces of the semiconductor substrate or substrate assembly using a vapor deposition process.
