  • Publication number: 20240113112
    Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.

  • Patent number: 9069357
    Abstract: A robot device includes a base station and a robot. The base station transmits guiding signals. The robot receives the guiding signal by three receivers. A receiver is disposed at the robot, and the other two receivers are disposed at the right and left of the receiver at different angles. The robot bypasses toward right or left according to the guiding signal received by the receivers. When the strength of the guiding signal received by the central receiver decreases, the robot stops bypassing to spin and searches the guiding signal again till the strength of the guiding signal received by the central receiver is a maximum value. The robot has a fine tuning to return to the base station to have a charge.
