  • Precursor compositions and methods
    Patent number: 8142847
    Abstract: Compositions including an amido-group-containing vapor deposition precursor and a stabilizing additive are provided. Such compositions have improved thermal stability and increased volatility as compared to the amido-group-containing vapor deposition precursor itself. These compositions are useful in the deposition of thin films, such as by atomic layer deposition.

  • Process for preparing or purifying Group III-A organometallic compounds
    Patent number: 4847399
    Abstract: Methods for forming or purifying organometallic compounds of elements of Group III-A of the Periodic Table. An intermediate compound is formed which is an adduct of the desired organometallic compound and a Group I-A or Group II-A compound. The adduct is nonvolatile, so volatile impurities are removed from the adduct by distillation. The adduct is decomposed to release the volatile organometallic compound, which is then distilled away from the nonvolatile remainder of the adduct. The method can be used to produce organometallic compounds which are substantially free of volatile metallic compounds and complexed solvents. A method of separating volatile Group II-B impurities from volatile Group III-A compounds is also disclosed.
