  • Patent number: 9349836
    Abstract: After formation of gate structures over semiconductor fins and prior to formation of raised active regions, a directional ion beam is employed to form a dielectric material portion on end walls of semiconductor fins that are perpendicular to the lengthwise direction of the semiconductor fins. The angle of the directional ion beam is selected to be with a vertical plane including the lengthwise direction of the semiconductor fins, thereby avoiding formation of the dielectric material portion on lengthwise sidewalls of the semiconductor fins. Selective epitaxy of semiconductor material is performed to grow raised active regions from sidewall surfaces of the semiconductor fins. Optionally, horizontal portions of the dielectric material portion may be removed prior to the selective epitaxy process. Further, the dielectric material portion may optionally be removed after the selective epitaxy process.

  • Patent number: 9337347
    Abstract: A semiconductor element having high mobility, which includes an oxide semiconductor layer having crystallinity, is provided. The oxide semiconductor layer includes a stacked-layer structure of a first oxide semiconductor film and a second oxide semiconductor film having a wider band gap than the first oxide semiconductor film, which is in contact with the first oxide semiconductor film. Thus, a channel region is formed in part of the first oxide semiconductor film (that is, in an oxide semiconductor film having a smaller band gap) which is in the vicinity of an interface with the second oxide semiconductor film. Further, dangling bonds in the first oxide semiconductor film and the second oxide semiconductor film are bonded to each other at the interface therebetween. Accordingly, a decrease in mobility resulting from an electron trap or the like due to dangling bonds can be reduced in the channel region.
