Phosphor filter, manufacturing method the phosphor filter, and semiconductor package using the phosphor filter

摘要

Stabilizing the variation of the color coordinate improve the yield and proposes a phosphor filter and a semiconductor package using a method of manufacturing the phosphor and the filter to simplify the flat gimbal of the phosphor layer to remove the occurrence of the yellow band. It presented fluorescent filter of the present invention, thereby projecting the incident light to white light. Fluorescent filters reputation of a transparent substrate; And a phosphor layer formed on one surface of a transparent substrate. Sikimeuroseo forming a phosphor layer on one surface of the glass plate in a uniform thickness in a manner such as squeeze spray or horizontal molding is made easier than in the prior art. The dispersion is stabilized by the color coordinates of the horizontal molded accurately than in the prior art. Therefore, the generation rate is reduced dramatically improves the yield of the irregular.
