Abstract

An IC device may include an array of transistors. The transistors may have separate gate electrodes. A gate electrode may include polysilicon. The gate electrodes may be separated from each other by one or more electrical insulators. The separated gate electrodes have shorter lengths, compared with connected gate electrodes, which can optimize the performance of the IC device due to local layout effect. Also, the IC device may include conductive structures crossing the support structures of multiple transistors. Such conductive structures may cause strain in the IC device, which can boost the local layout effect. The conductive structures may be insulated from a power plane. Alternatively or additionally, the IC device may include dielectric structures, which may be formed by removing gate electrodes in some of the transistors and providing a dielectric material into the openings. The presence of the dielectric structures can further boost the local layout effect.
