Provided are a package including a first conductive layer on a patterned layer, an insulating layer on the patterned layer burying the first conductive layer, a second conductive layer on an outer surface of the insulating layer, and a third conductive layer in the insulating layer electrically connecting the first conductive layer with the second conductive layer. A substrate is formed by printing or coating a paste- or ink-type insulator and conductor on a patterned layer formed on a sapphire wafer. No void is created between the substrate and LED chip, thus enhancing attachment strength. The ceramic-containing insulator is cured at a low temperature, thereby minimizing contraction of and damage to the wafer when the ceramic is fired. Printing methods utilizing viscous paste or ink solves problems with co-planarity of substrate that occur in existing wafer-to-wafer bonding processes and renders several steps of the existing substrate manufacturing process unnecessary.
