A method is provided for forming a dopant profile based on a surface of a wafer-like semiconductor component with phosphorus as a dopant. The method includes the steps of applying a phosphorus dopant source onto the surface, forming a first dopant profile with the dopant source that is present on the surface, removing the dopant source, and forming a second dopant profile that has a greater depth in comparison to the first dopant profile. In order to form an optimized dopant profile, the dopant source is removed after forming the first dopant profile, and precipitates that are crystallized selectively on or in the surface from the precipitates SixPy and SixPyOz are removed.
