The invention discloses a solid precursor source sublimation device and method for semiconductor processing, aiming to solve the problems of unstable volatilization and sublimation of the solid precursor source and low utilization rate of the solid precursor source. The invention includes a storage box, several trays installed in the storage box, an electric heating temperature control plate installed at the bottom of the tray, and a number of storage tanks for loading solid-state precursor sources are densely covered on the tray, and the storage boxes form a serpentine ventilation flow The storage box is provided with a carrier gas inlet and a mixed steam outlet, and the two ends of the air flow channel are respectively connected with the carrier gas inlet and the mixed steam outlet. This electrothermal solid-state precursor source storage and sublimation device can provide uniform and stable thermal energy for the volatilization and sublimation of the solid-state precursor source, and prevent the formation of low-resistance channels. The source can still be used, and the utilization rate of the solid precursor source is improved while providing a stable concentration of the solid precursor source vapor.
