Abstract: The disclosure provides a substrate processing apparatus. The substrate processing apparatus includes: an etching region and one or more aerosol absorption devices arranged outside a substrate inlet of the etching region. The aerosol absorption device includes one or more spraying pipes. The aerosol absorption device is capable of absorbing the aerosol of the etching solution from the etching region, thereby reducing the damage of the aerosol to the substrate processing components.
