Abstract
In a method for forming a barrier layer, the barrier layer is formed on a base layer having a three-dimensional structure before a dopant-containing layer is formed on the base layer. At this time, at least one of a film thickness, a film quality, and a film type of the barrier layer is controlled in a height direction of the three-dimensional structure by using an atomic layer deposition (ALD) process.
