Method of making a self protected thyristor |
摘要 |
The present invention is directed to a thyristor self-protected against overvoltage by the avalanche mechanism, the protection resulting from a laser scribed ring shaped groove cut in the top surface of the thyristor and extending into one base region of the thyristor whereby the forward blocking junction is contoured toward the reverse blocking junction under the ring shaped groove, and to the process for making the thyristor.
