Method of manufacturing semiconductor device and system for same

A non-transitory computer-readable medium having stored thereon computer executable instructions representing a method of generating a layout diagram, the layout diagram including layout cells which are organized into layout groups, each layout group including a central cell and a set of one or more of the cells which are adjacent to the central cell (adjacent cells), the computer executable instructions being executable by at least one processor to perform the method comprising generating the layout diagram including:

• selecting a candidate layout group from amongst the layout groups;
• within a database which stores predefined groups and corresponding parasitic capacitance (PC) descriptions thereof, each predefined group including a subject predefined cell and a corresponding set of one or more of the predefined cells which are adjacent to the subject predefined cell,
• searching the database for one amongst the predefined groups that is a substantial match to the candidate layout group;
• and
• when as substantial match is found, assigning the PC description of the matching predefined group to the candidate layout group.

A system for manufacturing a semiconductor device, the system comprising:

• at least one processor;
• at least one non-transitory computer readable storage medium that stores computer executable code;
• the at least one non-transitory computer readable storage medium, the computer program executable code and the at least one processor being configured to cause the system to generate a layout diagram including layout cells, generation of the layout diagram including:
• selecting a candidate cell from amongst the layout cells in the layout diagram;
• within a database which stores predefined cells and corresponding intracell parasitic capacitance (PC) descriptions thereof, searching the database for one amongst the predefined cells that is a substantial match to the candidate cell;
• and
• when a substantial match is found, assigning the intracell PC description of the matching predefined cell to the candidate cell.
