Abstract
The present invention relates to an encapsulating sheet for an optical semiconductor, including: a phosphor-containing layer containing a phosphor; and an encapsulating resin layer containing an encapsulating resin and being laminated on the phosphor-containing layer, in which, on the laminated surface therebetween, an edge of the phosphor-containing layer protrudes from an edge of the encapsulating resin layer, and a protruded length of the phosphor-containing layer is from 1 to 10 times a thickness of the encapsulating resin layer.
Claims6
An encapsulating sheet for an optical semiconductor, comprising:
- a phosphor-containing layer containing a phosphor;
- and an encapsulating resin layer containing an encapsulating resin and being laminated on the phosphor-containing layer, wherein, on the laminated surface therebetween, an edge of the phosphor-containing layer protrudes from an edge of the encapsulating resin layer, and a protruded length of the phosphor-containing layer is from 1 to 10 times a thickness of the encapsulating resin layer.
An optical semiconductor device obtained by disposing an encapsulating sheet for an optical semiconductor so that an encapsulating resin layer is opposite to an optical semiconductor element, followed by press molding using a concave die which has a concave structure having the same shape as in the encapsulating resin layer,
- wherein the encapsulating sheet for the optical semiconductor comprises:
- a phosphor-containing layer containing a phosphor;
- and the encapsulating resin layer containing an encapsulating resin and being laminated on the phosphor-containing layer, wherein, on the laminated surface therebetween, an edge of the phosphor-containing layer protrudes from an edge of the encapsulating resin layer, and a protruded length of the phosphor-containing layer is from 1 to 10 times a thickness of the encapsulating resin layer.
