Abstract

The present disclosure provides a method for manufacturing a light-emitting device, comprising: providing a first substrate; providing a semiconductor stack on the first substrate, the semiconductor stack comprising a first conductive type semiconductor layer, a light-emitting layer on the first conductive type semiconductor layer, and a second conductive type semiconductor layer on the light-emitting layer, wherein the semiconductor stack comprises a plurality of blocks of semiconductor stack separated from each other, and wherein the plurality of blocks of semiconductor stack comprise a first block of semiconductor stack and a second block of semiconductor stack; performing a separating step to separate the first block of semiconductor stack from the first substrate, and the second block of semiconductor stack remained on the first substrate; providing a permanent substrate comprising a first surface, a second surface, and a third block of semiconductor stack on the first surface; and bonding one of the first block of semiconductor stack and the second block of semiconductor stack to the second surface of the permanent substrate; wherein the third block of semiconductor stack is separated from the first substrate, and one of the first block of semiconductor stack and the second block of semiconductor stack which is bonded to the permanent substrate and the third block of the semiconductor stack comprise different optical characteristic value or an electrical characteristic value.
