Claim:
1. A method of depositing a layer on a substrate, comprising: (a) causing a relative movement between a substrate and reactors in a first direction by a first distance shorter than a length of the substrate during injection of gas by the reactors; (b) causing a relative movement between the substrate and the reactors in a second direction opposite to the first direction by a second distance shorter than the first distance during injection of the gas by the reactors; (c) repeating (a) and (b) for a first predetermined number of times; (d) causing a relative movement between the substrate and the reactors in the first direction by a third distance shorter than the length of the substrate during injection of the gas by the reactors; (e) causing a relative movement between the substrate and the reactors in the second direction by a fourth distance longer than the third distance during injection of the gas by the reactors.
