Measures against soft errors are becoming increasingly important as information and communications equipment becomes more sophisticated
There is a strong demand for miniaturization and power saving of high-performance information and communication devices used in high-speed communication networks such as the Internet, and this has led to the further integration of semiconductor devices. However, as the integration of semiconductor devices increases, how to deal with soft errors caused by neutrons from cosmic rays has become an issue for the entire industry.In the soft error test we provide, we irradiate the device under test with neutrons, measure and judge the errors that occur, and provide a service that clarifies the soft error tolerance in the actual environment. This test makes it possible to predict the failure and failure rate due to soft errors in electronic equipment, information communication equipment, server equipment, etc., whose failures have a serious impact on society.
In the society of the future, it will be necessary to build countermeasures based on the assumption that soft errors will occur in important equipment, etc., and to improve reliability, it will be necessary to respond to the occurrence of soft errors as a risk.Features
By implementing the soft error test service provided by our company, it is possible to predict the failure rate caused by soft errors in electronic equipment, information communication equipment, server equipment, etc., where failures and errors have a serious impact on society. increase. In addition, testing at the design stage of LSIs and ICs makes it possible to discover the locations where soft errors occur, enabling customers to take early countermeasures.

contents of the test
A small accelerator irradiates the device under test with neutrons from a low level and confirms that an error occurs. In addition, the failure rate is evaluated at the adjusted test level to confirm the effect of countermeasures with or without them.
