  • Publication number: 20190165155
    Abstract: A first FinFET device includes first fin structures that extend in a first direction in a top view. A second FinFET device includes second fin structures that extend in the first direction in the top view. The first FinFET device and the second FinFET device are different types of FinFET devices. A plurality of gate structures extend in a second direction in the top view. The second direction is different from the first direction. Each of the gate structures partially wraps around the first fin structures and the second fin structures. A dielectric structure is disposed between the first FinFET device and the second FinFET device. The dielectric structure cuts each of the gate structures into a first segment for the first FinFET device and a second segment for the second FinFET device. The dielectric structure is located closer to the first FinFET device than to the second FinFET device.

  • Patent number: 9941173
    Abstract: A system and method for a memory cell layout is disclosed. An embodiment comprises forming dummy layers and spacers along the sidewalls of the dummy layer. Once the spacers have been formed, the dummy layers may be removed and the spacers may be used as a mask. By using the spacers instead of a standard lithographic process, the inherent limitations of the lithographic process can be avoided and further scaling of FinFET devices can be achieved.
