Abstract

An organic thin film having excellent film qualities is formed. A vapor generating apparatus (20) is provided with an evaporation chamber (21), a jetting head (35) and a tank (31). A deposition material (39) is in the liquid state, stored in the tank (31) and supplied to the jetting head (35) from the tank (31). The jetting head (35) jets the deposition material (39), which has been supplied inside, from a jetting port (38), and places the deposition material on a heating member (25) inside the evaporation chamber (21). The jetting head (35) correctly supplies the deposition material (39) of a required quantity. Since only the required quantity of the deposition material (39) is heated, the organic thin film which does not deteriorate and has excellent film qualities is formed.

Description

technical field [0001] The present invention relates to a vapor generator and a vapor deposition device using the vapor generator. Background technique [0002] Organic electroluminescent (EL) elements are one of the most attention-grabbing display components in recent years, with excellent characteristics of high brightness and fast response. The organic electroluminescent element has a light emitting region that emits three different colors of red, green, and blue on a glass substrate. The light-emitting region is the anode electrode film, hole injection layer, hole transport layer, light-emitting layer, electron transport layer, electron injection layer and cathode electrode film stacked in this order, and red, Green or blue color. [0003] The hole transport layer, the light emitting layer, the electron transport layer, etc. are generally composed of organic materials, and a vapor deposition apparatus is widely used to form a film of such an organic material. [0004]...
