Popis: | Semiconductor wafer bonding is employed to fabricate very high efficiency transparent-substrate (TS) AlGaInP light-emitting diodes (LEDs) with projected lifetimes in excess of 100000 h under accelerated life test at an ambient temperature of 55/spl deg/C (70 A/cm/sup 2/). Furthermore, we demonstrate wafer-bonded TS AlGaInP red LEDs with external quantum efficiencies of 23.7% at 635.6 nm (20 mA, DC, 250/spl deg/C). |
