Abstract

A method for producing a semiconductor chip (100) is provided, in which, during a growth process for growing a first semiconductor layer (1), an inhomogeneous lateral temperature distribution is created along at least one direction of extent of the growing first semiconductor layer (1), such that a lateral variation of a material composition of the first semiconductor layer (1) is produced. A semiconductor chip (100) is additionally provided.
