CURABLE SILICONE RESIN COMPOSITION, SILICONE RESIN CURED MATERIAL, DAM MATERIAL, ENCAPSULANT, AND SEMICONDUCTOR DEVICE
The present invention is a curable silicone resin composition, the composition containing a linear organopolysiloxane, where the linear organopolysiloxane consists solely of a linear organopolysiloxane that has a less than 70% change rate of a contact angle of the linear organopolysiloxane to an Au substrate, the change rate being shown by the following expression (I): [{(contact angle of the linear organopolysiloxane to the Au substrate 2 seconds after dropping the linear organopolysiloxane)−(contact angle of the linear organopolysiloxane to the Au substrate 60 seconds after dropping the linear organopolysiloxane)}/(contact angle of the linear organopolysiloxane to the Au substrate 2 seconds after dropping the linear organopolysiloxane)]*100(%) (I). This provides a curable silicone resin composition that causes little contamination of surrounding members, and in which bleed-out hardly occurs.
