Electronic components used in space are exposed to a radiation environment that is incomparably harsher than that on Earth.
In such an environment, semiconductor devices are subject to the effects of radiation, which can cause degradation of their characteristics, malfunction, or damage.
The main effects of radiation are:
・TID (Total Ionizing Dose effects)
・SEE (Single Event Effects)
It is known that...
In the development of space equipment, evaluation of resistance to these radiation effects is extremely important.
As part of this effort, Macnica has begun offering support for the reliability of semiconductor devices for space use. This includes support for radiation resistance testing, inspection, and analysis of devices at external facilities both in Japan and overseas, as well as support for interfacing with the facilities.

What is ELDRS in space equipment development?
Enhanced Low Dose Rate Sensitivity (ELDRS) is a TID phenomenon.
This is device degradation caused by low dose-rate irradiation, especially in bipolar and BiCMOS IC components, and it has been found that irradiation with the same total dose (TID) can cause greater damage than high dose rates.
In addition, ELDRS evaluation is also included in several official documents that describe the requirements and procedures for TID testing, and the importance of ELDRS evaluation has been increasing in recent years.
Features of ELDRS test support services provided by Macnica
・Compatible with MLS-STD-883 TM1019, ESCC22900, etc.
・Consultation available regarding hardware and software required for testing
・Using facilities of US partner companies
・Submit irradiation test data and prepare reports
・We can also discuss specific test items and test conditions.

Use Case
・The project requirements required evidence of ELDRS evaluation.
・I would like to evaluate the ELDRS characteristics of ICs that I may use in the future.
・I have many questions about ELDRS test support and am unsure of how to proceed.
・We lack internal resources and need support to obtain irradiation test data
Please feel free to contact Macnica!
・Lack of knowledge/resources regarding radiation testing
・It is difficult to reserve domestic irradiation facilities, which may affect the plan.
- I am interested in the test conditions at overseas irradiation facilities
・We are considering adapting existing solutions for space use.
