A first dummy gate is disposed on an upper surface of the first portion of the field insulating material, and a second dummy gate at least partially extends into the second trench to the upper surface of the second portion of the field insulating material.
US08878307B2 Shared contacts for MOSFET devices
In one aspect, the present invention provides electronic devices that comprise a doped semiconductor shared contact between (a) a gate conductor region of at least one transistor and (b) a source/drain diffusion region of at least one transistor. One specific example of such as shared contact, among many others, is a doped SiGe shared contact between (a) a gate conductor region shared by an N-channel MOSFET and a P-channel MOSFET and (b) a drain diffusion region of an N-channel MOSFET or of a P-channel MOSFET.
US08878303B2 Geometric regularity in fin-based multi-gate transistors of a standard cell library
A method of optimizing a layout of an integrated circuit formed using fin-based cells of a standard cell library is provided. The method includes arranging cell rows of different track heights having standard cells. For each cell row, each of the standard cells includes sub-cell rows with sub-cells of one or more types. The sub-cells are interchangeable with one another to modify a device characteristic of the standard cell. The method also includes evaluating the integrated circuit to determine whether a performance metric of the integrated circuit has been satisfied. The method also includes identifying one or more standard cells to modify a device characteristic of the standard cell for satisfying the performance metric of the integrated circuit. The method further includes modifying the one or more standard cells until the performance metric of the integrated circuit is satisfied.
