Definitions
- the present invention is obtained by sealing a curable resin composition and a cured product thereof, a sealing agent using the curable resin composition, and a semiconductor element (particularly an optical semiconductor element) using the sealing agent.
- the present invention relates to a semiconductor device (especially an optical semiconductor device).
- sealing materials in optical semiconductor devices include barrier properties against corrosive gases such as SOx gas and thermal shock resistance (such as cracking or peeling of the sealing material even when a thermal shock such as a cold cycle is applied). (Characteristics that are less likely to cause malfunctions such as non-lighting of the semiconductor device) and reflow resistance (cracking or peeling of the sealing material even when extremely high temperature heat is applied during the reflow process) It is demanded that all of the above characteristics are satisfied at a high level at the same time.

- optical semiconductor devices for example, refer to Patent Document 1.
- the phenyl silicone-based encapsulant has a higher barrier property against corrosive gas than the conventionally used methyl silicone-based encapsulant, its properties are still insufficient. Actually, even when a phenyl silicone-based sealing material is used, there has been a problem that the corrosion of the electrode by the corrosive gas progresses with time in the optical semiconductor device, and the energization characteristics deteriorate.
