Spacer shim, slot die coater, and coating method using the same

Abstract

A spacer shim includes a plate-shaped shim body with predetermined width, length, and thickness; and a flow path having a groove in one surface of the shim body. The flow path include an inflow trench into which a coating solution is introduced in the thickness direction; a first discharge trench and a second discharge trench arranged to be spaced apart in the width direction to independently discharge a coating solution in the length direction; a first bending trench and a second bending trench configured to branch from one side and the other side of the inflow trench, respectively, and extend along the width direction and the length direction; and a first connection trench and a second connection trench configured to extend from the first bending trench and the second bending trench in the length direction, respectively, and communicate with the first discharge trench and the second discharge trench.
