Problems solved by technology

However, since such inks are different from nanoparticle inks in that they do not contain metal particles, they are transparent and have a low laser absorption rate. Therefore, the problems of requiring more light energy and increasing the pattern width also occur when patterning is produced.

Abstract

Disclosed is a method of fabricating a pattern, and more particularly is a method of fabricating a pattern by using laser. The method includes: a first step of forming an organometallic ink layer 20 on a substrate; a second step of curing the organometallic ink layer 20 into a semi-solid state; a third step of forming a pattern by irradiating laser onto the semi-solid organometallic ink layer 20, so that the irradiated portion of the organometallic ink layer 20 is changed into a solid state; and a fourth step of leaving only the pattern by removing the semi-solid organometallic ink layer 20.

Description

technical field [0001] The invention relates to a pattern manufacturing method, in particular, a method for manufacturing patterns by using laser light. Background technique [0002] Recently, the optical industry, display industry, semiconductor industry, and bioengineering industry have higher and higher requirements for thin film and high performance products. To comply with these requirements, the wiring or functional film layers that make up each component should be formed into smaller and more uniform patterns. Therefore, the manufacturing method of fine pattern is the basic technology of these industries. [0003] Conventionally, there have been many studies on the LDW method using nanoparticle ink as a non-exposed method of producing fine patterns. [0004] However, when nanoparticle inks with a size of tens of nanometers are directly irradiated with laser to form a pattern, it takes a long time for pattern formation due to a large amount of solvent and high temper...
