Abstract

A coating apparatus as well as coating method, wherein the coating apparatus comprises an objective table, a nozzle as well as a local environment generating mechanism. The objective table loads the base plate on its upper surface. The nozzle spurts out coating liquor from its frontend part, at the room above the objective table. The local environment generating mechanism partly supplies preceptive gas to the room containing coating liquor spurted out by the nozzle and the coating room of the coating sites of the base plate coated with the coating liquor so as to the coating of the coating liquor is executed at prescribed environment.

Description

technical field [0001] The present invention relates to a coating device and a coating method, and more particularly, to a coating device and a coating method for spraying a coating liquid such as an organic EL material from a nozzle onto a substrate mounted on a stage to coat the substrate. Background technique [0002] Conventionally, various developments have been made on coating devices for coating coating liquids on objects to be processed such as substrates. For example, in a device for manufacturing an organic EL (Electro Luminescence: electroluminescence) display device, such a coating device is used: the main surface of a substrate such as a glass substrate loaded on a stage is sprayed in a predetermined pattern shape through a nozzle. A hole transport material or an organic EL material is applied. In this coating device, a coating liquid (organic EL material or hole transport material) is ejected from a nozzle at a predetermined pressure. Specifically, after the ...
