SLOT DIE COATER

Abstract

A slot die coater includes a lower die, an upper die disposed above the lower die and coupled to the lower die, and a shim member disposed between the lower die and the upper die and forming a plurality of discharge ports in a width direction. The lower die includes an injection port through which a slurry can be introduced into the slot die coater, a cavity configured to increase the slurry introduced through the injection port in the width direction and cause the slurry to flow through the discharge ports, and an extension portion that connects the injection port and the cavity and is configured to cause the slurry to expand in the width direction from the injection port to the cavity.
