Abstract
In an embodiment a method for manufacturing a semiconductor device include providing a growth substrate, depositing an n-doped first layer, depositing an active region on the n-doped first layer, depositing a second layer onto the active region, depositing magnesium (Mg) in the second layer and subsequently to depositing Mg, depositing zinc (Zn) in the second layer such that a concentration of Zn in the second layer decreases from a first value to a second value in a first area of the second layer adjacent to the active region, the first area being in a range of 5 nm to 200 nm.
