Abstract

A method includes: transmitting a sublimated raw material together with a carrier gas to a raw material trapping part where the raw material is temporarily trapped; calculating a difference between trapped amounts of the raw material trapped in the raw material trapping part during a predetermined period of time as an increase in trapped amount; obtaining at least one of a period of time required to reach the trapped amount to a target value and a trapping rate of the raw material, based on the increase, a period of trapping time, and a trapped amount measured at the time of completing trapping the raw material; refilling the raw material into the raw material trapping part based on the at least one of the period of refilling time and the trapping rate; and sublimating the raw material and supplying the same together with the carrier gas to a consumption area.
