PURPOSE:To obtain the master-slice LSI, in which cells, density thereof is high and performance thereof is also high, are arranged in a two element shape, by disposing a contact position of the gate of a transistor so as to extremely avoid the use of buried wiring. CONSTITUTION:The positional relationship of a pair of contacts S1, M1 to the gate wiring of a P type transistor P and an N type transistor N forming a pair is reversed to the positional relationship of another contact pair S2, M2. A layout pattern of the wiring of one part of a flip-flop circuit with a reset is shown in the figure. A pattern in which oblique lines rising to the right are formed represents signal line wiring, and a pattern in which oblique lines falling to the right are formed represents a power supply line. P Type source-drain 41 constituting a pair of a TG1 and a TG2 are connected directly by Al, and buried wiring (E1-F1) need not be used excessively. |
