Problems solved by technology

However, epoxy resins have a problem in that epoxy resins have low transmittance for light in the blue to UV wavelength region and also show deteriorated light resistance
However, the disadvantage of silicone resin is that it has poor heat resistance and its surface is sticky after curing.

Abstract

The present invention relates to a silicone resin. The silicone resin of the present invention can be used to advantage in applications involving the encapsulation of semiconductor elements, such as the light-emitting elements of light-emitting diodes.

Description

technical field [0001] The invention relates to a silicone resin. Background technique [0002] High-brightness LED products using compound semiconductors of GaN compounds such as GaN, GaAlN, InGaN or InAlGaN have been obtained as LEDs (Light Emitting Diodes), especially as blue or UV LEDs having an emission wavelength of about 250nm to 550nm. In addition, high-definition full-color images can be formed using a technology that combines red and green LEDs with blue LEDs. For example, a technique of producing white LEDs by combining blue LEDs or UV LEDs with phosphors is known. There has been an increasing demand for such LEDs for conventional lighting or backlighting in liquid crystal displays (LCDs). [0003] Epoxy resins with high adhesive strength and excellent dynamic durability have been widely used as LED encapsulants. However, epoxy resins have a problem in that epoxy resins have low transmittance for light in the blue to UV wavelength region and also show deteriora...
