  • Publication number: 20090262564
    Abstract: An improved circuit wiring layout provides smooth circuit wiring in a peripheral circuit region adjacent to a memory cell region of a semiconductor memory device, and eliminates a write-speed limiting factor. Forming a metal (instead of a metal silicided polysilicon) wiring layer to be connected to a gate layer, to transmit an electrical signal to the gates of FET (e.g., MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistors formed in the peripheral circuit region; the metal wiring layer is formed (e.g., using one metal damascene process), on a layer different from a word line layer formed on the gate layer (e.g., using another metal damascene process), thereby obtaining a layout of a peripheral circuit region having a reduced area and without using a silicide process.
