Claim:
1. A method for atomic layer deposition, comprising the steps of, providing a housing; providing a moving bed which passes through the housing of the moving bed including a reaction surface; providing a first precursor gas at a first precursor gas input; simultaneously providing a second precursor gas at a second precursor gas input spaced apart from the first precursor gas input a distance L; and controlling the speed of the moving bed and amounts of the first precursor gas released into the housing, the amounts of the first precursor gas being less than available reaction sites of the reaction surface, thereby leading to consumption of the first precursor gases prior to the first precursor gas reaching the second precursor gas input such that the first precursor gas and the second precursor gas are not intermixed.
