  • Publication number: 20190164837
    Abstract: A semiconductor structure with cutting depth control and method for fabricating the same are provided. In the method for fabricating the semiconductor device, at first, fins protruding from a substrate are formed. Next, source/drain devices are grown on both ends of the fins. Then, an inter-layer dielectric layer crossing the fins and enclosing the source/drain devices is deposited. A metal gate structure enclosed by the inter-layer dielectric layer is formed between the source/drain devices. And then, a replacement operation is performed to replace a portion of the inter-layer dielectric layer with an isolation material, thereby forming an isolation portion that adjoins the metal gate structure and is located between the adjacent source/drain devices. Thereafter, a metal gate cut operation is performed, thereby forming an opening in the metal gate structure and an opening in the isolation portion, and an insulating material is deposited in the openings.

  • Publication number: 20160086665
    Abstract: A 3D memory device includes an improved dual gate memory cell. The improved dual gate memory cell has a channel body with opposing first and second side surfaces, charge storage structures on the first and second side surfaces, and a gate structure overlying the charge storage structures on both the first and second side surfaces. The channel body has a depth between the first and second side surfaces less than a threshold channel body depth, combined with the gate structure which establishes an effective channel length of the cell greater than a threshold length. The combination of the channel body depth and effective channel length are related so that the cell channel body can be fully depleted, and sub-threshold leakage current can be suppressed when the memory cell has a high threshold state under a read bias.

  • Patent number: 9252156
    Abstract: A method of forming an interlayer conductor structure. The method includes forming a stack of semiconductor pads coupled to respective active layers for a circuit. The semiconductor pads include outside perimeters each having one side coupled to a respective active layer. Impurities are implanted along the outside perimeters to form outside lower resistance regions on the pads. Openings are then formed in the stack of the semiconductor pads to expose a landing area for interlayer conductors on a corresponding semiconductor pad and to define an inside perimeter on at least one of the semiconductor pads. Inside lower resistance regions are formed along the inside perimeters by implanting impurities for interlayer conductor contacts and configured to overlap and be continuous with the corresponding outside lower resistance region.
