    摘要: A base is formed of a material, such as SiC, having mechanical characteristics higher than those of silicon for forming a semiconductor layer, and the base and the semiconductor layer are bonded through an insulating layer. After bonding, an SOI substrate is formed by mechanically separating the semiconductor layer from the base, and the separated semiconductor layer is reused for forming the subsequent SOI substrate. Thus, a large SOI substrate having a diameter of 400 mm or more, which has been difficult to obtain by conventional methods, can be obtained.

    摘要: A method of manufacturing a semiconductor device including a sputtering process for forming a barrier film mainly having tantalum or tantalum nitride on an interlayer insulator formed by sputtering using a xenon gas. The sputtering process may include a step of forming one barrier film mainly composed of tantalum nitride on a substrate by sputtering using a xenon gas by applying a RF bias, and a step for forming another barrier film mainly composed of tantalum on the first barrier film by sputtering using a xenon gas without applying the RF bias. The barrier film may be formed by changing the RF bias continuously, and forming the interlayer insulator side by applying the RF bias, and forming the wiring side without applying the RF bias.

    摘要: For equalizing the rising and falling operating speeds in a CMOS circuit, it is necessary to make the areas of a p-type MOS transistor and an n-type MOS transistor different from each other due to a difference in carrier mobility therebetween. This area unbalance prevents an improvement in integration degree of semiconductor devices.The NMOS transistor and the PMOS transistor each have a three-dimensional structure with a channel region on both the (100) plane and the (110) plane so that the areas of the channel regions and gate insulating films of both transistors are equal to each other. Accordingly, it is possible to make the areas of the gate insulating films and so on equal to each other and also to make the gate capacitances equal to each other. Further, the integration degree on a substrate can be improved twice as much as that in the conventional technique.
