GB/T 4937.44-2025 Semiconductor devices—Mechanical and climatic test methods—Part 44:Neutron beam irradiated single event effect(SEE) test method for semiconductor devices
Basic Information
Scope
This document describes a test method for measuring the single-event effect (SEE) of high-density integrated circuits, including the data retention capability of semiconductor devices subjected to atmospheric neutron irradiation from cosmic rays. The single-event effect sensitivity of semiconductor devices is measured through neutron irradiation at a known dose rate. This test method is applicable to any type of integrated circuit. Note 1: High-voltage semiconductor devices can also exhibit single-event effects, including single-event burnout (SEB) and single-event gate latch-up (SEGR), etc. This document does not cover this part. Please refer to IEC 62396-4. Note 2: In addition to high-energy neutrons, thermal neutrons with energy less than 1 eV can also cause soft errors in some devices. This document does not cover this part. Please refer to IEC 62396-5.
