  • Patent number: 8899883
    Abstract: A mine roof support system includes an elongated anchor rod or tendon having a rigid non-deformable distalmost anchoring end portion, and one or more axially deformable portions which are configured to deform in the event load forces exceed a threshold force approximating the forces during a rock burst or rock dilation event. The rigid anchoring portion is provided with primary anchor members such as ribs, grooves, studs and the like. The primary anchor members are configured to reduce bar plasticity, and fixedly secure and retain the rigid portion in place in a drill hole. In the event rock forces exceed the threshold force, the plastically deformable portions elongate with the dilating rock to accommodate and absorb the rock forces.

  • Patent number: 8697523
    Abstract: A method of fabricating a FINFET includes the following steps. A plurality of fins is patterned in a wafer. A dummy gate is formed covering a portion of the fins which serves as a channel region. Spacers are formed on opposite sides of the dummy gate. The dummy gate is removed thus forming a trench between the spacers that exposes the fins in the channel region. A nitride material is deposited into the trench so as to cover a top and sidewalls of each of the fins in the channel region. The wafer is annealed to induce strain in the nitride material thus forming a stressed nitride film that covers and induces strain in the top and the sidewalls of each of the fins in the channel region of the device. The stressed nitride film is removed. A replacement gate is formed covering the fins in the channel region.
