Abstract:
A semiconductor device including: an insulating substrate; a semiconductor element mounted on the insulating substrate; an internal printed circuit board disposed on the semiconductor element; and a sealing member that seals the semiconductor element, the internal printed circuit board, and at least a portion of the insulating substrate. The sealing member is made of a sealant that includes a resin and a pigment, and that initially has a chromatic, white, or gray color, and the sealing member degrades, thereby causing color of a front surface thereof to change to a degree recognizable by a user after the semiconductor device has been in use under a prescribed condition for a prescribed duration.

Claim (Index 7):
A method of estimating remaining life of a semiconductor device that includes a sealing member made of a sealant, the method comprising:\n heating a test sealant that has a same composition as a composition of the sealant in the semiconductor device at prescribed heating temperatures for prescribed durations; acquiring a relationship among the heating temperatures, heating durations, and resulting changes in color of the test sealant, by observing the color of the test sealant while the test sealant is being heated; and estimating the remaining life of the semiconductor device that has been operated, by evaluating color of a front surface of the sealing member in accordance with the relationship acquired in the step of acquiring said relationship.
