Abstract
A substrate surface information detection device and a substrate surface information detection method are disclosed. The device includes a spray source and an image sensor, wherein the spray source is configured to uniformly spray droplets onto a surface of a substrate-under-test or form a liquid flow on the surface of the substrate-under-test, and the image sensor is configured to record image information of the droplets or the liquid flow. According to the substrate surface information detection device and substrate surface information detection method, defects on the surface of the substrate before the PI coating can be prevented and avoided, the production time can be shortened, and the production efficiency can be promoted and the product yield can be improved.
