A partial oxide film (31) with well regions formed therebeneath isolates transistor formation regions in an SOI layer (3) from each other. A p-type well region (11) is formed beneath part of the partial oxide film (31) which isolates NMOS transistors from each other, and an n-type well region (12) is formed beneath part of the partial oxide film (31) which isolates PMOS transistors from each other. The p-type well region (11) and the n-type well region (12) are formed in side-by-side relation beneath part of the partial oxide film (31) which provides isolation between the NMOS and PMOS transistors. A body region is in contact with the well region (11) adjacent thereto. An interconnect layer formed on an interlayer insulation film (4) is electrically connected to the body region through a body contact provided in the interlayer insulation film (4).

摘要:
The present invention provides a semiconductor IC and a method for designing the same which adjusts the clock skews on a chip without additional delay circuit. A decrease in design time is realized when the semiconductor IC includes hard megacells (whose functions have been confirmed) or standard cell blocks. In the case of a semiconductor IC including hard megacells and a standard cell blocks, each megacell and standard cell block according to the present invention has sub-clock buffers on every row, for example, sub-clock buffers on the row and sub-clock buffers on the row in the megacell. The adjustment needed for accommodating clock skews on a chip is determined by calculating a delay time for the various IC chip blocks. Next, sub-clock buffers are chosen based on a result of a calculation for the delay time. Finally, the wiring design is completed which minimizes clock skew.
