| titleOfInvention | Novel silicon carbide avalanche diode array yield and breakdown voltage testing method |
| abstract | The invention discloses a novel method for testing yield and breakdown voltage of a silicon carbide avalanche diode array, which comprises the following steps: randomly selecting more than two devices in the novel silicon carbide avalanche diode array to test I-V characteristics to obtain the average value V of breakdown voltage b (ii) a Take 1.1V b As the highest test voltage, applying bias voltage to a single device in the novel silicon carbide avalanche diode array, and gradually increasing the bias voltage to the highest test voltage; with current magnitudes of 10 respectively ‑7 A and 10 ‑6 A is used as a breakdown point and a current limiting point, and whether the device is available is preliminarily judged; and applying bias voltage to a single device to judge whether the device is damaged due to high-voltage test. The invention reduces the testing period of the SiC-based APD array, improves the precision of testing the breakdown voltage of the SiC-based APD, improves the working consistency of devices in the array, reduces the damage of the devices caused by testing and improves the safety of testing personnel. |
