Title:
MANUFACTURING METHOD FOR OPTICAL SEMICONDUCTOR ELEMENTS HAVING PHOSPHOR LAYERS AND SEALING LAYERS
Document Type and Number:
WIPO Patent Application WO/2016/178397
Kind Code:
A1
Abstract:
This manufacturing method for optical semiconductor elements having phosphor layers and sealing layers, comprises: an element arrangement step for arranging a plurality of optical semiconductor elements at one side in the thickness direction of a phosphor sheet so as to be spaced from one another; a first cutting step for cutting the phosphor sheet between the plurality of optical semiconductor elements so as to form gaps penetrating the phosphor sheet in the thickness direction, to form a plurality of phosphor layers corresponding to the plurality of optical semiconductor elements, respectively; a sheet forming step for forming a sealing sheet so as to fill the gaps and cover side surfaces of the optical semiconductor elements; and a second cutting step for cutting the sealing sheet in the thickness direction to form a plurality of sealing layers corresponding to the plurality of optical semiconductor elements and the plurality of phosphor layers, respectively.
