SEMICONDUCTOR LIGHT EMITTING DEVICE WITH A CONTACT FORMED ON A TEXTURED SURFACE |
摘要 |
A device includes a semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region. The semiconductor structure includes an n-contact region and a p-contact region. A cross section of the n-contact region comprises a plurality of first regions wherein portions of the light emitting layer and p-type region are removed to expose the n-type region. The plurality of first regions are separated by a plurality of second regions wherein the light emitting layer and p-type region remain in the device. The device further includes a first metal contact formed over the semiconductor structure in the p-contact region and a second metal contact formed over the semiconductor structure in the n-contact region. The second metal contact is in electrical contact with at least one of the second regions in the n-contact region. |
