The body bias control system provides a switch circuit having an area in which the body bias is controlled independently of its outside portion, for controlling the supply of body bias in the vicinity of the area. Preferably three types of switches are provided for switching the body bias to suitable levels for a standby mode, a mode of normal operation and a mode of high-speed operation.

摘要： A technique permitting the reduction in size of a semiconductor device is provided. In a BGA type semiconductor device with a semiconductor chip flip-chip-bonded onto a wiring substrate, bump electrodes of the semiconductor chip are coupled to lands formed at an upper surface of the wiring substrate. The lands at the upper surface of the wiring substrate are coupled electrically to solder balls formed on a lower surface of the wiring substrate. Therefore, the lands include first type lands with lead-out lines coupled thereto and second type lands with lead-out lines not coupled thereto but with vias formed just thereunder. The lands are arrayed in six or more rows at equal pitches in an advancing direction of the rows. However, a row-to-row pitch is not made an equal pitch. In land rows which are likely to cause a short-circuit, the pitch between adjacent rows is made large, while in land rows which are difficult to cause a short-circuit, the pitch between adjacent rows is made small. By so doing, both prevention of a short-circuit and improvement of the layout density of lands are attained at a time.

For example, in the case where the width of a first Cu wiring is not smaller than about 0.9 μm and is smaller than about 1.44 μm, and the width of a second Cu wiring and the diameter of a plug are about 0.18 μm, there are arranged two or more plugs which connect the first wirings and the second Cu wirings electrically with each other.

摘要： There is provided a high-density mask ROM operable at a high speed. With the mask ROM, respective source lines are disposed so as to be shared by memory cells in respective columns adjacent to each other, and bit lines are disposed so as to correspond to the respective columns of the memory cells. Further, the dummy cells are disposed for the respective columns of the memory cells. The dummy cells are each made up of a series-circuit including a first switching transistor that is turned into the conducting state in response to a signal potential on a dummy word line (DWL), and a second switching transistor 17 for coupling an adjacent source line to the bit line corresponding thereto in response to a potential of the source line in a column corresponding thereto. The memory cells each are made up of one unit of a transistor and a data storage formed by mask wiring. At the time of reading data, a potential of the source line in a select column is caused to undergo a change, whereupon there occurs a potential difference between a pair made up of the bit line as selected to which the memory cells as selected are coupled, and a reference bit line with the dummy cells coupled thereto, so that it is possible to execute readout of data by detecting the potential difference.
