Application scenarios of silane: cross-border from semiconductors to biomaterials
The purity requirements for silane vary depending on the application field:
In the field of photovoltaics, the passivation contact structure on the back of N-type batteries requires 5N (99.999%) or higher purity silane, with a usage increase of 50% compared to P-type batteries.
Semiconductor field: requires 7-9N ultra-high purity, used for integrated circuit manufacturing, coating reflective glass, etc.
In emerging fields such as silicon carbon anodes, advanced ceramics, composite materials, and biomaterials, silane is used as a precursor or modifier to enhance material properties.
Case: In the production of crystalline silicon solar cells, high-purity silane forms an amorphous silicon layer through vapor deposition to improve the conversion efficiency of the cell; In semiconductor manufacturing, silane is used to deposit silicon oxide or silicon nitride thin films to protect chips from contamination.
