MULTI-LAYER STRUCTURE ENCAPSULATING METHOD FOR OPTICAL ELEMENT

摘要

The present invention relates to a multi-layer structure encapsulating method for an optical element and, more particularly, to a multi-layer structure encapsulating method for an optical element having a multi-layer structure in which a polysilazane layer is formed as a separate layer in an upper part or a lower part of a silicon layer, thereby reducing outgassing, and an optical element comprising an encapsulant of a multi-layer structure produced thereby.
