| titleOfInvention | Screening method for semiconductor device |
| abstract | PURPOSE: To select the defect through measurement of the reverse current when the balance is kept between the temperature on the element surface and the peripheral temperature by leaving the airtight-sealed semiconductor device into the lowtemperature atomsphere of 0W5°C. n CONSTITUTION: The airtight-sealed device is left more than 5 hours at a high temperature of 100°C or more to vaporize the micro amount or water within the container, and then the inside of the airtight container is kept under 0W °C. At the same time, the dry air of under dew point-30°C is flown. When the temperature on the element surface is balanced with the peripheral temperature, the reverse voltage is applied to the pn-junction to measure the reverse current. If the humidity within the container is high, the internal relative humidity becomes more than 100% as the room temperature lowers down. As a result, the dew condensation is given to increase the reverse current suddenly. In this way, the screening removal is given to obtain high-reliability device. n COPYRIGHT: (C)1979,JPO&Japio |
