Abstract:
1. A manufacturing method of an LED (light emitting diode) chip, comprising: providing a substrate; forming a light emitting layer comprising an n-type semiconductor layer and a p-type semiconductor layer on the substrate; forming a pair of electrodes electrically connected to the n-type semiconductor layer and the p-type semiconductor layer, respectively; connecting a bonding wire to at least one of the electrodes by adding melted metal to a portion of a top surface of the at least one of the electrodes, a ratio between an area of the portion of the top surface of the at least one of the electrodes and the top surface of the at least one of the electrodes being no less 6:10; and solidifying the melted metal to form a bonding pad to connect the bonding wire and the at least one of the electrodes together.
