Patent ID: 7838311

Claim:
A process for producing a light-emitting semiconductor device, comprising: (i) mixing at least one low-molecular silane represented by the following general formula (1) or at least one silanol represented by the following general formula (2) with an alcohol solution containing an alkoxysiloxane to prepare a mixture solution, the amount of the silane or silanol being from 10% by weight to 50% by weight based on the dry weight of an encapsulating material to be formed; (ii) applying the mixture solution to a light-emitting element; (iii) vaporizing the alcohol solvent in the mixture solution applied and drying the residual mixture to thereby form the encapsulating material; and (iv) curing the encapsulating material In general formula (1), R 1 s each independently represent a methyl group or an ethyl group; and R 2 represents an alkyl group having 1-20 carbon atoms or a phenyl group which may have one or more hydrocarbon groups each having 1-8 carbon atoms In general formula (2), R 3 represents an ethyl group.
