  • Publication number: 20180138250
    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.

  • Patent number: 9853149
    Abstract: The present disclosure relates an integrated circuit (IC) and a method for manufacturing same. A polysilicon layer is formed over a first region of a substrate and has a plurality of polysilicon structures that are packed with respect to one another to define a first packing density. A dummy layer is formed over a second region of the substrate and has a plurality of dummy structures that are packed with respect to one another to define a second packing density, where the first packing density and second packing density are substantially similar. An inter-layer dielectric layer is formed over the first region and second region of the substrate. Dishing of at least the second region of the substrate concurrent with a chemical-mechanical polish is generally inhibited by the first packing density and second packing density after forming the inter-layer dielectric layer.
