The invention discloses a method for manufacturing a silicon nitride film with high tensile stress, comprising the following steps of: depositing a first silicon nitride film layer on a silicon substrate, treating the first silicon nitride film by using plasma; depositing a second silicon nitride film layer on the first silicon nitride film layer, treating the second silicon nitride film by using plasma; and performing ultraviolet irradiation on the multilayer silicon nitride film. The manufacturing method provided by the invention can be used for manufacturing a silicon nitride film with the smallest stress of 1.8GPa at a lower manufacturing cost, the silicon nitride film can be applied to an NMOS(N-channel Metal Oxide Semiconductor) device for greatly increasing the electromobility, and the production process is quite simple.
