    摘要： The present invention relates to a method of manufacturing an LED device which emits light of multi-wavelengths. The invention also relates to a method of manufacturing LED devices which emit light of high quality from throughout the whole surface in a uniform manner. In particular, utilizing the manufacturing method of LED devices which emit light of multi-wavelengths makes it possible to produce LED devices of high quality in a simple and cost-efficient way, not by using adhesives, but by a sputtering or PLD method. In addition, since the characteristics of the desired emitted light can be controlled by controlling the amount and type of the phosphors during the manufacture of sputtering targets, high quality LED devices can be manufactured easily.

    摘要： Disclosed herein is a method of qualitatively analyzing high-molecular additives in a metal plating solution, including: removing sulfate ions and metal ions from a metal plating solution; and qualitatively analyzing the metal plating solution, from which sulfate ions and metal ions are removed, using Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectroscopy (MALDI-TOF MS). The method is advantageous in that the structure and molecular weight of high-molecular additives present in very small amounts in a plating solution can be accurately measured while maintaining the specific structure and molecular weight thereof without degrading the high-molecular additives.
