Abstract
A lifting-off method and a manufacturing method for a thin film transistor (TFT) array substrate using the same are provided. A lifting-off method comprises forming a cavitation jet flow by using a lifting-off solution, and impacting a to-be-lifted-off surface of a substrate by means of the cavitation jet flow to remove a photoresist and a film deposited on the photoresist over the to-be-lifted-off surface. The disclosure may be applied to manufacturing processes for semiconductor devices or TFT array substrate.
