Semiconductor devices are provided including an active layer, a gate structure, a spacer, and a source/drain layer. The active layer is on the substrate and includes germanium. The active layer includes a first region having a first germanium concentration, and a second region on both sides of the first region. The second region has a top surface getting higher from a first portion of the second region adjacent to the first region toward a second portion of the second region far from the first region, and has a second germanium concentration less than the first germanium concentration. The gate structure is formed on the first region of the active layer. The spacer is formed on the second region of the active layer, and contacts a sidewall of the gate structure. The source/drain layer is adjacent to the second region of the active layer.

Semiconductor devices having gate structures and methods of manufacturing the same

Disclosed are an organic light emitting display and a method of manufacturing the same. The organic light emitting includes a first substrate, a first electrode, an organic light emitting layer, and a second electrode. The first substrate includes a pixel region showing an image and a peripheral region surrounding the pixel region. The first electrode is formed in the pixel region of the first substrate. The organic light emitting layer is formed on the first electrode. The second electrode is formed on the organic light emitting layer and extends to the peripheral region. An auxiliary electrode is formed on the second electrode to contact the second electrode on an entire surface of the first substrate, thereby applying a voltage having the same voltage level as that of the second electrode.
