Abstract
PURPOSE: To decrease time aging and to make stable the operating characteristics, by using the resin low in thermal distortion transition temperature for sealing resin.
CONSTITUTION: As the resin for the semiconductor device sealing GaAs LED with resin, the resin less than 100°C in thermal distortion transition temperature is used. For example, if the resin R1 and R2 in which the thermal distortion transition temperature is more than 100°c are used, the optical output of the sealed GaAs LED is deteriorated to 10% of the initial value with the power application for 1000 hours, but with the resin in which transition temperature is less than 100°C used, the optical output is more than 90% of the initial value.
