Talk:Radiation hardening

Cleanup tag removal
I have removed the cleanup tag from this article after rewriting the second paragraph (which had been flagged in the cleanup tag) and re-arranging the start of the article.

Any queries, add them to my talk page. Tswsl1989 15:28, 29 March 2007 (UTC)

Proposed merge from Nuclear hardness
I think these two articles should be merged. As Radiation hardening is longer than Nuclear hardness, I think they should be merged into Radiation hardening. RupertMillard (Talk) 17:33, 14 October 2007 (UTC)

susceptibility to interference from electromagnetic radiation
"... reduce the susceptibility to interference from electromagnetic radiation..." To me this seems wrong. Interference from electromagnetic radiation seems to imply imunity to radio wave energy which is a large topic in itself. The word 'Radiation' in common usage generally implies nuclear sources, gamma rays have wavelengths orders of magnitude shorter than any standard 'electromagnetic radiation' testing.

 * I jumped at the same sentence. There is a big difference between electromagnetic radiation and ionizing radiation as well as between interference and damage. I changed "interference from electromagnetic radiation" into "radiation damage" which I hope was the intended meaning of the sentence? Ulflund (talk) 20:12, 30 May 2012 (UTC)

Proposed Split, and correction of titles
It appears to me that this article contains too many different topics, and the current outline is not logic at all.

I would like to propose the following new structure:


 * New article: Radiation Environments, would contain what is now in section 2. In fact there is a lot more to write about different radiation environments on Earth and in Space.
 * Existing category: Radiation Effects, connects the different types of effects, like those on different materials, semiconductors, human tissues, as well as more specific articles as nuclear accidents etc.
 * New article:  Radiation Effects on Semiconductors, would contain section 3 (and hopefully much more as this section is very incomplete).
 * Existing article: Radiation Hardening is only section 4,5,8, but a lot of content is missing yet.

A lot of clean-up is needed, of course.

Any comments are appreciated. Bogl4712 (talk) 20:53, 14 June 2011 (UTC)

These articles are closely related to Radiation Environments is already mostly covered in Space weather. Radiation Effects on Semiconductors should be harmonized and cross-linked with the above articles to avoid redundancy. There should be a forward from RHBD to Radiation hardening.

 * Radiation,
 * Ionizing Radiation,
 * Cosmic ray,
 * Galactic cosmic ray,
 * Radiation protection,
 * Space radiation,
 * Space weather,
 * MOSFET,
 * Single event upset.

Comment and question
1. "This ionization may cause a highly localized effect similar to the transient dose one - a benign glitch in output, a less benign bit flip in memory or a register or, especially in high-power transistors, a destructive latchup and burnout."

This sentence does not sound right. I think it needs some work.

2. "Choice of substrate with wide band gap, which gives it higher tolerance to deep-level defects"

Wouldn't it be more appropriate to use "high band gap" rather than "wide band gap"?

3. Resultant effects section mentions CMOS a number of times, which seems to be more specific than necessary. Shouldn't this be MOS instead? "...thus affecting bipolar devices more than CMOS ones." — Preceding unsigned comment added by Miles60 (talk • contribs) 21:21, 8 May 2013 (UTC)

4. Single-Event Latchup (SEL) is marked as "Hard error, irreversible" - which is not true in all cases. As the section specifies, the latch up condition is cleared when the device is power cycled. Permanent damage (or a hard error) only occurs if the latch up causes dangerous currents to flow through transistor. It is entirely possible (and common enough) for devices to latch up, and be recovered to full operation with a power cycle. — Preceding unsigned comment added by 194.62.210.160 (talk) 09:31, 29 January 2019 (UTC)
