JEDEC JESD57 Ionizing Dose and Neutron Effects Testing
The JEDEC standard JESD57 addresses the critical need for semiconductor and microchip manufacturers to ensure their products can withstand harsh environments, particularly ionizing radiation and neutron exposure. These conditions are common in spacecraft, nuclear power plants, medical devices operating near radiation sources, and high-altitude avionics. Ionizing radiation and neutrons can induce defects that may lead to permanent damage or temporary operational issues.
Our testing service is designed to assess the reliability of your semiconductor products under JESD57 standards by simulating real-world exposure conditions. This includes ionizing dose (gamma, X-ray) and neutron effects, ensuring that critical components perform reliably in demanding environments. The test process involves precise control over environmental parameters such as temperature, humidity, and pressure to accurately simulate the intended use environment.
Our expert team uses advanced instrumentation, including high-purity germanium detectors for gamma radiation measurement, ionization chambers for neutron flux monitoring, and calorimeters for accurate dose quantification. Specimen preparation requires a cleanroom environment to ensure that test samples are free from contamination, which could skew the results.
The testing process involves several key steps:
- Preparation of the semiconductor or microchip specimen in a controlled environment
- Simulation of ionizing radiation and neutron exposure using calibrated sources
- Ongoing monitoring of temperature, humidity, and pressure to maintain consistent test conditions
- Data collection on performance metrics such as leakage current, threshold voltage shift, and threshold voltage spread
The testing report provides detailed insights into the product's response under JESD57 conditions. This information is crucial for quality managers and compliance officers to ensure that their products meet regulatory requirements and industry standards.
Our service is not only about meeting specifications but also providing valuable data that can inform R&D engineers in optimizing designs for greater reliability and performance. Procurement teams benefit from this testing as it helps them select suppliers who adhere to the highest quality standards.
