Germane
Germane (CAS: 7782-65-2, GeH4, MW: 76.67) is an inorganic compound and the simplest germane. This highly flammable, toxic gas is a critical precursor in the semiconductor industry for depositing germanium-containing films via chemical vapor deposition (CVD) and atomic layer deposition (ALD). It is also employed in chemical synthesis and materials science research.
Semiconductor Manufacturing
Germane is a key precursor for the deposition of germanium (Ge) and silicon-germanium (SiGe) alloys used in advanced microelectronic devices. It enables the formation of thin films with specific electronic properties through CVD and ALD processes.
Materials Science
In materials science, germane is utilised for the synthesis of novel germanium-based nanomaterials and compounds. Its controlled decomposition allows for the precise engineering of material structures at the nanoscale.
Chemical Synthesis
As a versatile reagent, germane can be used in various chemical synthesis pathways to introduce germanium into organic and inorganic molecules. It serves as a building block for more complex germanium-containing compounds.
