Abstract:
The present disclosure, in some embodiments, relates to a method of forming an integrated circuit. The method is performed by forming a gate structure over a substrate, and selectively implanting the substrate according to the gate structure to form first and second source/drain regions on opposing sides of the gate structure. A first MEOL structure is formed on the first source/drain region and a second MEOL structure is formed on the second source/drain region. The first MEOL structure has a bottommost surface that extends in a first direction from directly over the first source/drain region to laterally past an outermost edge of the first source/drain region. A conductive structure is formed to contact the first MEOL structure and the second MEOL structure. The conductive structure laterally extends from directly over the first MEOL structure to directly over the second MEOL structure along a second direction perpendicular to the first direction.
Abstract:
A method includes the operations below. A first and second layout patterns corresponding to a first and second area are placed. Third layout patterns corresponding to a first continuous fin over the first area and second area, and corresponding to a second fin including separate portions spaced apart by a first recess over the first area are placed. A fourth layout pattern, corresponding to a dummy gate, at the recess portion and between the first layout pattern and the second layout pattern, is placed to generate a layout design of a semiconductor device. A side of the second area facing the first recess is substantially flat, and the semiconductor device is fabricated by a tool based on the layout design. A first length of the first continuous fin is equal to a sum of a second length of the second fin and a third length of the first recess.
Abstract:
The present disclosure, in some embodiments, relates to an integrated circuit. The integrated circuit includes first and second source/drain regions within a substrate. A gate structure is over the substrate between the first and second source/drain regions. A middle-end-of-the-line (MEOL) structure is over the second source/drain region. The MEOL structure has a bottommost surface that continuously extends in a first direction from directly contacting a top of the second source/drain region to laterally past an outer edge of the second source/drain region. A conductive structure is on the MEOL structure. A second gate structure is separated from the gate structure by the second source/drain region. The conductive structure continuously extends in a second direction over the MEOL structure and past opposing sides of the second gate structure. A plurality of conductive contacts are configured to electrically couple an interconnect wire and the MEOL structure along through the conductive structure.
Abstract:
A semiconductor device includes a substrate and fins. The fins are formed on a first area and a second area of the substrate. The first area includes a first recess. The second area is located with respect to the first area. The first recess is disposed at a side of the first area, and faces the second area. A projection area of the first recess on a side of the second area is substantially flat.
Abstract:
The present disclosure relates to a method and apparatus for accurate RC extraction. A pattern database is configured to store layout patterns and their associated 3D extraction parameters. A pattern-matching tool is configured to partition a design into a plurality of patterns, and to search the pattern database for a respective pattern and associated 3D extraction parameters. If the respective pattern is already stored in the pattern database, then the associated 3D extraction parameters stored in the database are assigned to the respective pattern without the need to extract the respective pattern. If the respective pattern is not stored in the pattern database, then the extraction tool extracts the pattern and stores its associated 3D extraction parameters in the pattern database for future use. In this manner a respective pattern is extracted only once for a given design or plurality of designs. Moreover, the extraction result may be applied multiple times for a given design simultaneously, speeding up computation time. The extraction result may also be applied to a plurality of designs simultaneously.
Abstract:
A system and method of determining a cell layout are disclosed. The method includes receiving a circuit design corresponding to a predetermined circuit design, the circuit design having a first set of cells and abutting adjacent cells in the first set of cells, the abutted cells having a first boundary pattern therebetween. The first boundary pattern is exchanged with a second boundary pattern based on a number or positions of signal wires in the first boundary pattern. A cell layout for use in a patterning process can then be determined, the cell layout including the second boundary pattern.
