A method of mounting an LED chip, which is intended to suppress void-generation inside an eutectic bonding without use of flux. This method includes a step of eutectically bonding a first metal layer (e.g., AuSn layer) on a rear surface of the LED chip, with a metal ground layer on a dielectric substrate (mounting member). This method includes a step of providing a second metal layer having the same metal component as the first metal layer, to the top surface of the metal ground layer on a dielectric substrate; and subsequently connecting the LED chip and the dielectric substrate by way of eutectically bond while the dielectric substrate is heated at its bottom surface remote from the metal ground layer to melt the second metal layer by heat source (heater or the like). |
