LBT solution method for fabricating LBT solution and method for fabricating LBT thin film and electric device using the same

摘要

The present invention relates to a process for the preparation of LB Ti thin film and the electronic device manufacturing method of the tea solution LB, LB Ti solution and using the same.; LB method of manufacturing a tea solution according to the present invention comprises the steps of preparing a first solution by dissolving a bismuth salt of bismuth (Bi-acetate) in the solvent (Solvent); Comprising: dissolving the first acid solution for bismuth (Acid) preparing a second solution of bismuth; The method comprising dissolving a lanthanum salt of lanthanum (La-acetate) in acid to prepare a titanium solution; Preparing a bismuth lanthanum solution to the second solution and the bismuth lanthanum solution was stirred for one another; And the bismuth lanthanum titanium into the solution to the titanium (Ti) source comprising: stirring a predetermined time; made, including, made of a structure of a _{La x Bi 4-x Ti 3} O 12 (LBT), 0≤X≤2 have the condition. In addition, the coating on the electrode the LB tea solution using spin-coating method to produce an electronic device such as a capacitor.; Therefore, it is capable of making an electronic element such as the capacitor there is no fatigue phenomenon has a greater capacitance than the effect.
