  • Germanium complexes with amidine derivative ligand and process for preparing the same
    Patent number: 8663736
    Abstract: Provided is a germanium complex represented by Chemical Formula 1 wherein Y1 and Y2 are independently selected from R3, NR4R5 or OR6, and R1 through R6 independently represent (Ci-C7) alkyl. The provided germanium complex with an amidine derivative ligand is thermally stable, is highly volatile, and does not include halogen components. Therefore, it may be usefully used as a precursor to produce high-quality germanium thin film or germanium-containing compound thin film by metal organic chemical vapor deposition (MOCVD) or atomic layer deposition (ALD).
