Abstract
The present disclosure relates to an organic light emitting device including a logic device that comprises a dummy pattern and a merged spacer, and an associated fabrication method. In some embodiments, the organic light emitting device is disposed over a substrate. The logic device is coupled to the organic light emitting device, and comprises a pair of source/drain regions disposed within the substrate and separated by a channel region. A gate structure overlies the channel region and comprises a gate electrode and a dummy pattern separated from the gate electrode by a merged spacer. By arranging the dummy pattern and the merged spacer between the gate electrode and the source/drain regions, a distance between the gate electrode and the source/drain region is enlarged, and therefore reducing the gate induced drain leakage (GIDL) effect.
