Abstract

There is provided a method of producing a copper precursor and a copper precursor produced by using the same. The method of producing a copper precursor includes: preparing an aqueous solution including a copper salt or a hydrate thereof; preparing a mixture by mixing urea (CO(NH2)2) with the aqueous solution; and synthesizing the copper precursor by heating the mixture at a temperature of 100 to 120Β° C.

[0001] Cross References to Related Applications

[0002] This application claims priority from Korean Patent Application No. 10-2012-0041519 filed with the Korean Intellectual Property Office on Apr. 20, 2012, the entire contents of which are hereby incorporated by reference into this application. technical field

[0003] The present invention relates to a copper precursor (copper precursor) and its preparation method, and more specifically, to a copper precursor preparation method and the copper precursor prepared by this method. The method does not need to generate intermediate Copper precursors can be prepared from intermediates, and copper precursors can be synthesized at low temperatures. Background technique

[0004] Since copper (Cu) has the same level of specific resistance as silver (Ag), and has a low cost of about one percent of silver (Ag), it is currently used as wires for most electronic components.

[0005] Copper (Cu) is mostly used in the form of powder in ...
