Abstract:
A system and method for efficiently creating layout for a standard cell are described. A standard cell to be used for an integrated circuit uses a full trench silicide strap as drain regions for a pmos transistor and an nmos transistor. Multiple unidirectional routes in metal zero are placed across the standard cell where each route connects to a trench silicide contact. Power and ground connections utilize pins rather than end-to-end rails in the standard cell. Additionally, intermediate nodes are routed in the standard cell with unidirectional routes.
Abstract:
A system and method for creating a layout for a vertical gate all around standard cell are described. Metal gate is placed all around two vertical nanowire sheets formed on a silicon substrate. A gate contact is formed on the metal gate between the two vertical nanowire sheets. Gate extension metal (GEM) is placed above the metal gate at least on the gate contact. A via for a gate is formed at a location on the GEM where a local interconnect layer is available to be used for routing a gate connection. Local metal layers are placed for connecting local routes and power connections.
Abstract:
A system and method for fabricating metal patterns are described. Multiple mandrels are formed on a first polysilicon layer which is on top of a first oxide layer. Each mandrel uses a second polysilicon on top of a first nitride. A spacer oxide and a spacer nitride are formed on the sidewalls of the mandrels to create double spacers. A second oxide layer is deposited followed by removing layers until the first nitride in the mandrels is reached. Areas are etched based on a selected method of multiple available methods until the first oxide layer is etched providing trenches for the metal patterns. Remaining materials on the first oxide layer are removed followed by metal being deposited in the trenches in the first oxide layer.
Abstract:
Integrated circuit layouts are disclosed that include metal layers with metal tracks having separate metal sections along the metal tracks. The separate metal sections along a single track may be electrically isolated from each other. The separate metal sections may then be electrically connected to different voltage tracks in metal layers above and/or below the metal layer with the separate metal sections. One or more of the metal layers in the integrated circuit layouts may also include metal tracks at different voltages (e.g., power and ground) that are adjacent to each other within a power grid layout. The metal tracks may be separated by electrically insulating material. The metal tracks and the electrically insulating material between the tracks may create capacitance in the power grid layout.
Abstract:
A system and method for fabricating non-planar devices while managing short channel and heating effects are described. A semiconductor device fabrication process includes forming a non-planar device where the body of the device is insulated from the silicon substrate, but the source and drain regions are not insulated from the silicon substrate. The process builds a local silicon on insulator (SOI) while not insulating area around the source and drain regions from the silicon substrate. A trench is etched a length at least that of a channel length of the device while being bounded by a site for a source region and a site for a drain region. The trench is filled with relatively thick layers to form the local SOI. When nanowires of a gate are residing on top of the layer-filled trench, a second trench is etched into the top layer for depositing gate metal in the second trench.
Abstract:
A semiconductor device fabrication process includes forming insulating mandrels over replacement metal gates on a semiconductor substrate with first gates having sources and drains and at least one second gate being isolated from the first gates. Mandrel spacers are formed around each insulating mandrel. The mandrels and mandrel spacers include the first insulating material. A second insulating layer of the second insulating material is formed over the transistor. One or more first trenches are formed to the sources and drains of the first gates by removing the second insulating material between the insulating mandrels. A second trench is formed to the second gate by removing portions of the first and second insulating materials above the second gate. The first trenches and the second trench are filled with conductive material to form first contacts to the sources and drains of the first gates and a second contact to the second gate.
Abstract:
Methods, a computer readable medium, and an apparatus are provided. A method includes and the computer readable medium is configured for decomposing an overall pattern into a first mask pattern that includes a power rail base pattern and into a second mask pattern, and generating on the second mask pattern a power rail insert pattern that is at least partially aligned with the power rail base pattern of the first mask pattern. The apparatus is produced by photolithography using photolithographic masks generated by the method.
