Abstract: An ALD or digital CVD apparatus and method for microparticles are proposed. The apparatus and the method use an impact, which is caused by the pulsed introduction of a precursor or a purging gas to be introduced into a reactor, without additional vibration or rotation of the reactor, so as to inhibit the agglomeration of particles to be applied to a surface and enable dispersion to be maximized, thereby enabling each particle to be uniformly applied, and simultaneously preventing the loss, in the reactor during processing, of powder to be coated without an additional separate filter or filler. A deposition reactor has a structure in which at least two overlapping reactors are provided. A reactant or a purging gas directly flows into an inner reactor in which a chemical reaction occurs. A purging step is simultaneously carried out in inner and outer reactors.
