Method for fabricating semiconductor structure, and solid precursor delivery system

摘要

A method for fabricating a semiconductor structure is provided, including: providing a solid precursor having a first average particle size; solving the solid precursor in an organic solvent into an intermediate; recrystallizing the intermediate to form solid granules, wherein the solid granules has a second average particle size larger than the first average particle size; vaporizing the solid granules to form a film-forming gas; and depositing the film-forming gas on a substrate to form a resistance film. A method for modifying a resistance film source in a semiconductor fabrication and a solid precursor delivery system are also provided. The method for fabricating a semiconductor structure in the present disclosure can remove small particles or ultra-small particles from solid precursor, and does not need extra time to dump cracked solid precursor.
