The third approach is about the concept of an ITO direct Ohmic contact structure on GaP window layer. The direct Ohmic contact structure is performed by the deposition of an AuBe diffused thin layer and the following activation process on the surface of a Mg-doped GaP window layer. The presence of this thin AuBe diffused layer yields the Be dominant metallic surface layer and significantly reduces the barrier height between the ITO and p-GaP layer. Via the modification of contact structure, not only the brightness was significantly increased but the reliability was comparable to the conventional LED without this structure.

第三个研究为一种具有直接欧姆接触在p型磷化镓窗层与氧化铟锡界面的制程方法，於本研究中并无习知砷化镓欧姆接触层的存在，我们利用金/金铍金属藉由热退火程序，使其金铍原子在磷化镓窗层表面形成具金属特性之薄膜层，降低磷化镓与氧化铟锡接触产生之接面能障；另外，该元件在氧化铟锡直接欧姆接触於磷化镓窗层下，除亮度具明显提升外，在稍大电流(20毫安培)元件可靠度测试下，亦未有明显衰减情形发生。
