The space environment is harsh for semiconductor devices! ?
Last time, we discussed the effects of space radiation on semiconductor devices.
He explained that "the space environment contains cosmic radiation, making it a harsh environment for semiconductor devices."
This time, we will introduce in detail the "TID" that was introduced in the article.
Learn about TID (total dose effect)
TID (Total Ionizing Dose Effects) is a type of effect that occurs when a semiconductor device is exposed to a large amount of gamma rays, proton beams, electron beams, etc.
The electric charges generated by this ionization process accumulate in the insulating film inside the device, causing degradation of electrical characteristics.
Specific phenomena include an increase in power supply current and leakage current, and changes in operation timing.
As the word "total"suggests,
It depends on the total dose: how much radiation was received by the device?
For this reason, the impact of TID on semiconductor devices is as follows:
This needs to be based on a prediction of "how much dose will there be during the mission?"
What devices are resistant to TID (Total Dose Effect)?
Rad-Hardand Rad-Tolerant devices with TID resistance (semiconductors for space use)
Confirmation (testing) of TID resistance is carried out by the manufacturer.
On the other hand, for other devices (consumer parts, automotive parts),
Most of them have not been tested for TID resistance,
If necessary, you should carry out your own resistance assessment.
TIDresistance evaluation involves TID testing in a radiation exposure facility.
In this TID test, the device under evaluation is exposed to a radiation field containing gamma rays, electron beams, etc.
We check how the characteristics of the device change.
Products that pass these tests are
It is used in equipment launched into space as a device that is expected to function normally in space.
In the explanation so far, What is TID?"How much radiation were you exposed to? Dependence on
TIDThe resistant devices are"TID Those who passed the test and were selected Did you understand that this is the case?
In the next article, we will introduce the "TID We will be taking a deeper look into the topic of "Countermeasures against this virus." Please look forward to it.
Macnica to go when it comes to TID (total dose effect)!
Macnica also accepts consultations regarding "Radiation Resistance Testing and Evaluation (TID/SEE) requirements."
In addition to consulting about radiation testing,
We also provide support for the following "reliability of semiconductor devices for space use":
- Implementation support for tests, inspections, and analyzes at external facilities in Japan and overseas, and interface with facilities
- Conducting non-destructive testing using Macnica 's in-house X-ray inspection equipment
If you have any problems regarding "Space Semiconductors", please feel free to contact us using the inquiry form below.
We will support you based on Macnica 's"abundant experience"and"high technology."
