Claim:
1. A method for preparing monogermane gas, comprising: injecting an aqueous alkali solution of starting materials and an aqueous acid solution into a first channel and a second channel, respectively, the aqueous alkali solution containing germanium dioxide (GeO mixing the injected aqueous alkali solution of the starting materials and the aqueous acid solution in a third channel connected to the first channel and the second channel, and reacting the mixed solutions to produce monogermane gas and a reaction solution; and discharging the produced monogermane gas and the reaction solution out of the third channel, wherein reaction heat generated in the third channel is absorbed by a coolant circulating in a coolant circulation unit disposed adjacent to the third channel, wherein the third channel is a microchannel.
