Claim Text:
1. A coating module, suitable for coating a liquid onto a substrate, comprising: a planar slot consisting of: two plates, wherein the planar slot is constructed only by the two plates therebetween with two plane surfaces in parallel, an end of the slot has a slot inlet, the other end of the slot has a slot outlet, and one of the two plates has an injecting port, wherein the material of the two plates comprises silicon wafer or glass; and a curved diversion structure, connecting the injecting port and the slot inlet with at least one curved periphery from the injecting port to the planar slot, wherein the liquid is configured to enter the diversion structure via the injecting port, then uniformly flow to the slot inlet through the diversion structure, then flow into the slot via the slot inlet, and then uniformly outflow from the slot via the slot outlet, so that the liquid flows from a hole and disperses as a thin film through the curved diversion structure to directly form a thin film through the planar slot to be coated onto the substrate.
