Verticle extends Cu-base hexagonal LED chip range to UV #Verticle #UVLED #CuSubstrate

Figure 3 shows that Verticle’s Cu-base UV-LED chip has higher radiant flux than a lateral UV-LED chip fabricated on the same epiwafer. Furthermore, the firm’s UV-LED chip can be driven at higher current than other vertical chips fabricated on different substrate materials, the firm claims. Verticle’s GaN/Cu UV-LED chip does not saturate over 1A, while GaN/W and GaN/sapphire UV-LED chips start to saturate above 500mA, so the GaN/Cu chip has higher heat dissipation capability than GaN on other substrates, the firm claims. Verticle says this shows that its Cu-base UV-LED chip has advantages for applications where high current injection and good thermal properties are required.
