Abstract

A semiconductor chip comprises: a semiconductor body which comprises a semiconductor layer sequence suitable for emitting electromagnetic radiation of a first wavelength range from its front side; and a first wavelength-converting layer on at least one first partial region of the front side of the semiconductor body with a first wavelength conversion substance, which converts radiation of the first wavelength range into radiation of a second wavelength range, which is different from the first wavelength range, wherein at least one second partial region of the front side is free of the first wavelength-converting layer. An optoelectronic component comprising such a semiconductor chip and a method for producing the semiconductor chip are furthermore described.
