Claim 0:
1. An atomic layer deposition method comprising:
injecting a first precursor into a chamber along a first direction and turning on a bias power supply to attract the first precursor to a substrate;
injecting a second precursor into the chamber along a second direction perpendicular to the first direction and turning on the bias power supply to attract the second precursor to the substrate;
injecting a first inert gas into the chamber along the first direction and turning off the bias power supply to purge an unnecessary part of the first precursor or an unnecessary part of the second precursor or by-products; and
injecting a second inert gas into the chamber along the second direction and turning off the bias power supply to purge the unnecessary part of the first precursor or the unnecessary part of the second precursor or the by-products.
