An optoelectronic semiconductor chip includes a semiconductor body with an active region provided for generating electromagnetic radiation, a first mirror layer provided for reflecting the electromagnetic radiation, a first encapsulation layer formed with an electrically insulating material, and a carrier provided for mechanically supporting the first encapsulation layer, the first mirror layer and the semiconductor body. The first mirror layer is arranged between the carrier and the semiconductor body. The first encapsulation layer is arranged between the carrier and the first mirror layer. The first encapsulation layer is an ALD layer.
