    摘要： An exemplary cell library includes a first plurality of types of standard cells. Each of the first plurality of types of standard cells includes threshold voltage adjusting patterns. The upper and the lower boundaries of the threshold voltage adjusting patterns contact the upper and lower boundaries of the cell frame and the distances between the left and right boundaries of the-threshold voltage adjusting patterns and the cell frame are set appropriately. Accordingly, it is possible to place standard cells including transistors with different threshold voltages at arbitrary positions without increasing the area of a circuit block or the design cost.
