Abstract
The whole body of a semiconductor device with its pn junction exposed ends covered by insulating glass is subjected to the exposure to radiation having an energy of higher than 0.5 MeV in terms of the reduced energy of electron beams while the semiconductor device is maintained at temperatures higher than 300.degree. C., and preferably higher than 350.degree. C. As a result, the life time of the minority carriers in the semiconductor device can be shortened without increasing the leakage current in the reverse direction.
