  • Patent number: 10101662
    Abstract: A developing method includes rotating a wafer. A developer solution is dispensed onto the rotated wafer through a first nozzle. The first nozzle is moved from a first position to a second position. The first position and the second position are over the wafer and within a perimeter of the wafer when viewed from a top of the wafer. The developer solution is dispensed through the first nozzle when moving the first nozzle from the first position to the second position. The first nozzle is moved back from the second position to the first position immediately after the first nozzle is moved from the first position to the second position. The developer solution is dispensed through the first nozzle when moving the first nozzle from the second position to the first position.

  • Publication number: 20180208076
    Abstract: Control for an auto-balancing transportation device and the transportation devices having such controls. The controls monitoring system power and power use and generating a corrective response when the difference between system (or device or available) power and power use is below a given threshold. Power use may be calculated using a velocity parameter which provides a measure that more accurately reflects the environment conditions in which the device is being use, and provides benefits over a one-speed speed limit. Various corrective responses including pitch back and alarms, including those to a user-borne device are disclosed.
