hi, i want to know about radiation hardened chip,can u guys please
help me out????
Dielectric Isolation between transistors, along with (?)tungston
resistors was one way i heard about.

Maybe you could tell us what type of chip you are looking for. Any
idea of the radiation environment in which this chip might be operated?

hi ,robert,thanx 4 d rply.can u give me d address of sm websites frm
where i cud get the information about these chips.actually i want to
know in detail about abt this chip.Or else can u xplain 2 me abt this
chip,i hope u will we knowing a lot abt it.

the questio is messup what radiation heat atomic gamma you define that maybe somone will give you an answer.

A number if ICs (analog and digital) were made for the military for
use in satellites, where radiation is a concern.
I think that SOS was another process used.

Alrighty,

Let me begin with the background texts:

Messenger and Ash, The Effects of Radiation on Electronic Systems
Ma And Dressendorfer, Ionizing Radiation Effects in MOS Devices
Clays and Simoen, Radiation Effects in Advanced Semiconductor
Materials and Devices
Messenger and Ash, Single Event Phenomena

As I am typing this, there is a conference being held in Honolulu, HI
on the very subject for which you are interested. It is called the
Nuclear and Space Radiation Effects Conference. The proceedings from
this conference are published in December in a special issue of the
IEEE Transactions on Nuclear Science. You can find the program for
this year's conference on their website:

http://www.nsrec.com

A very informative, publicly available issue of The Aerospace
Corporation's magazine on the space radiation environment, device
design for that environment and testing of those devices:

http://www.aero.org/publications/crosslink/summer2003/index.html

You'll find more information, many links and a database of parts
tested on NASA Goddards Radiation Effects & Analysis Home Page:

http://radhome.gsfc.nasa.gov

You will also find many articles on reliability and radiation hardened
devices on NASA's Office of Logic Design website:

http://klabs.org

Just the tip of the iceberg, but I hope this helps. Let me know if
you have any specific questions you'd like answered.

Any chance you could write in English?

I only worked in one company that did radhard, and that was during the
dark ages. It did go on epi, which was not common at the time. I doubt
you could find CMOS that isn't on epi nowadays.
