Patent ID: 6898778

Claim:
A method of manufacturing a semiconductor integrated circuit comprising: storing a cell library in a database, said cell library containing data of at least a plurality of first voltage-activated transistors having the same channel conduction type, electrically connected in parallel or in series between a first power supply terminal and an output terminal, and a body region and a source region of at least one first voltage-activated transistor near said output terminal are electrically connected and have the same potential, and a plurality of second voltage-activated transistors having the same channel conduction type, electrically connected in series or in parallel to a second power supply terminal and said output terminal, and a body region and a source region of at least one second voltage-activated transistor near said output terminal are electrically connected and have the same potential; designing a logic circuit; locating said cell library from said database to a memory space on the basis of said logic circuit by using a design automation system; and linking said cell library in said memory space using said design automation system and creating logic circuit data.
