  • Publication number: 20180323181
    Abstract: A fabricating method of a light-emitting apparatus including the following steps is provided. An adhesive layer having first adhesive bump groups including first adhesive bumps is provided. A transfer stamp picks up first light-emitting device groups including first light-emitting devices. The transfer stamp approaches the adhesive layer such that the first light-emitting devices of one first light-emitting device group are in contact with the first adhesive bumps of one corresponding first adhesive bump group. When the first light-emitting devices are in contact with the first adhesive bumps, the remaining first light-emitting devices on the transfer stamp are staggered with the first adhesive bumps and are not in contact with the adhesive layer. The transfer stamp is kept away from the adhesive layer such that the first light-emitting devices stay on the first adhesive bumps of the corresponding first adhesive bump group.
