Radiation-resistant capacitor housing material

How to make a device more radiation resistant?

It has been found that these effects can be alleviated by alternating the rate of growth of oxide layers and controlling composition of gases used to promote the growth and annealing of the oxide. Basically, it is the process modification, which is required to make device more radiation resistant.

What are the three components of outer space radiation?

Solar radiation, galactic cosmic radiation and trapped particles in the geomagnetic sphere are the three components of outer space radiation. Solar radiation is composed of light nuclei with high energy. Energy of solar protons lies between 10 and 100 MeV.

How to design a radiation-hardened electronic system?

Electronic system Design of radiation-hardened electronic system begins with the analysis of nuclear environment encountered. It must be determined precisely what kind of radiation is likely to be encountered, total dose, dose rate and radiation energy .

How to reduce radiation absorption in a circuit?

Rigorous checking of interconnecting cables, wire loops and ground paths is a must to ensure that they are minimized for absorption of radiation energy. Use only those components and materials for circuits which statistically exceed the specified radiation levels.

What are the effects of radiation on CMOS transistors?

CMOS transistors have low power requirement and therefore good for space and military applications. The two major effects of radiation on CMOS circuits are: (a) threshold voltage shift and gain degradation of individual transistors due to total dose and (b) logic upset, latch up and circuit burn out due to large transient burst of radiation .

Does reducing the thickness of gate oxide improve radiation resistance?

Reducing the thickness of gate oxide tox, improves the radiation resistance and the gate voltage shift scaling with tox2 and tox3 for a given dose have been observed . Thinner gate oxides are required for small channel lengths, so higher density processes tend to improve the radiation resistance even without a special hardening technique .
