The invention discloses a method of using an SMA wire to drive an active part to move, which comprises steps: the temperature of a first SMA wire rises to a first temperature, the temperature of a second SMA wire rises to a second temperature, the first temperature is higher than an SMA wire deformation critical temperature, the second temperature is lower than or equal to a deformation critical temperature, the first SMA wire at the first temperature and the second SMA wire at the second temperature are located at a first contraction position and a second stretching position after stabilization, and the active part moves to a desired position corresponding to the first contraction position and the second stretching position under drive of the first SMA wire and the second SMA wire.

A substrate etching method and a substrate processing device, the substrate etching method includes: S1: placing a substrate to be processed into a reaction chamber; S2: supplying etching gas into the reaction chamber; S3: turning on an excitation power supply to generate plasma in the reaction chamber; S4: turning on a bias power supply to apply bias power to the substrate; S5: turning off the bias power supply, and meanwhile, starting to supply deposition gas into the reaction chamber; S6: stopping supply of the deposition gas into the reaction chamber, and meanwhile, turning on the bias power supply; S7: repeating steps S5-S6, until the etching process is completed. In the whole etching process, the etching operation is always performed, and the deposition operation is performed sometimes. Therefore, during the deposition operation, the plasma in the reaction chamber can etch away at least a part of deposited polymers formed by the deposition operation on a sidewall of an etched section, so that the sidewall of the etched section of the substrate is smooth.

The present application discloses a method for using SMA wires to drive the movement of movable parts, including: raising the temperature of the first SMA wire to a first temperature, and raising the temperature of the second SMA wire to a second temperature, wherein the first temperature is higher than that of the SMA wire The deformation critical temperature, the second temperature is lower than or equal to the deformation critical temperature, the first SMA line at the first temperature and the second SMA line at the second temperature are respectively in the first contraction position and the second stretching position after stabilization, so The movable part is driven by the first SMA wire and the second SMA wire to move to a desired position corresponding to the first retracted position and the second stretched position.
