Semiconductor structures and substrates thereof, and methods of manufacturing semiconductor structures and substrates thereof
Abstract:
This application provides a semiconductor structure and substrate thereof, a method of manufacturing the semiconductor structure and substrate thereof. The substrate includes a plurality of unit areas, each of the unit areas includes at least two subunit areas, each of the subunit areas is provided with a groove, the groove is opened from a back side of the substrate; and in one of the unit areas, preset opening ratios of the subunit areas are different. A light-emitting layer is grown on a front side of the substrate; and in one of the unit areas, light-emitting wavelengths of the light-emitting layer in the subunit areas are different.
