LIGHT EMITTING DIODE AND A METHOD FOR MANUFACTURING THE SAME, CAPABLE OF IMPROVING LIGHT EXTRACTING EFFICIENCY BY FORMING THE LIGHT EMITTING DIODE INTO A WIRE-BONDING TYPE

摘要

PURPOSE: A light emitting diode and a method for manufacturing the same are provided to reduce the internal defect density of a semiconductor layer by blocking the transfer of electrical potential generated based on the difference of a coefficient of thermal expansion and lattice constant between a substrate and a seed layer.;CONSTITUTION: A buffer layer(12) and a seed layer(14) are formed on a base substrate(10). A double film pattern(17) is formed on the seed layer. The double film pattern includes a window part and a mask part exposing the seed layer. A first semiconductor layer(21) is horizontally grown on the double film pattern. A second semiconductor layer(22) is arranged on the first semiconductor layer.;COPYRIGHT KIPO 2011
