Problems solved by technology

However, the above method has some disadvantages
First, exposure to electromagnetic environments such as ultraviolet light may produce undesired device degradation
Second, chemical corrosion may produce undesired device contamination due to the use of chemicals
Third, these methods require multiple steps to complete, increasing the time and expense of manufacturing
Also, the nature of the organic solution deposited within the borehole may allow the organic solution to spread onto the surface of the adjacent bank

Embodiment approach 1

[0154] In this example for SU-8 TM 2000 The contact angles of water and anisole on glue materials are discussed.

[0155] As mentioned above, the SU-8 TM Glue 2000 was used as the polymeric material to form the banks to direct the flow of the organic solution into the respective wells. Contains SU-8 TM The banks of the 2000 glue were embossed with an embossed formation having a grid and grooves with a width and height of 2 microns. Table 1 shows the contact angles (θx, θy) of water and anisole and the change in contact angle (Δθ).

[0157]

[0158] The term "post-cure" refers to the SU-8 TM 2000 Glue Results Status. SU-8 TM Glue 2000 is first exposed to UV light to start the crosslinking process and then heated to complete the crosslinking. SU-8 in this state TM 2000 glue is called "post-cure".

[0159] As can be seen from Table 1, when water is placed on the imprint formations with a width an...

Abstract

A method of manufacturing an organic electronic or optoelectronic device, the method comprising the steps of: (a) providing a substrate having a plurality of banks formed thereon with alternating well formations formed therebetween, the surface of said banks having imprint formations formed thereon of a dimension conferring a selected wetting property to the surface of said banks that is different from the surface of said wells; and (b) depositing an organic solution into said well formations, wherein the wetting property of said banks causes any organic solution deposited thereon to be at least partially repelled.

Description

technical field [0001] The present invention generally relates to a method of fabricating an organic electronic or optoelectronic device. Background technique [0002] Organic electronic or optoelectronic devices generally comprise active organic materials located between electrode layers. In order to obtain a device with good performance, it is usually necessary to form a pattern on the electronic or / and organic material layer. [0003] Known methods of patterning devices include steps such as exposing the device to electromagnetic radiation to chemically change the molecular structure, forming the pattern by chemical etching, and removing the etched material. However, the above method has some disadvantages. First, exposure to electromagnetic environments such as ultraviolet light may produce undesired device degradation. Second, chemical etching may produce undesired device contamination due to the use of chemicals. Third, these methods require multiple steps to be pe...
