How to prevent TID (total dose effect)?
Previously, as a phenomenon unique to the universe,
We introduced TID (Total Ionizing Dose effects) and SEE (Singe Event Effects).
These are events that could potentially have a negative effect on semiconductors used in satellites launched into space.
What kind of measures can be taken?
This time, we will focus on "TID" and introduce some typical shielding countermeasures.

Protect semiconductor devices from TID! What is that method?
TID is a phenomenon that occurs when a semiconductor device is exposed to a large amount of radiation, such as gamma rays, proton beams, or electron beams.
Therefore, one measure to prevent this radiation from entering a semiconductor device is to use a shield.
As shown in Figure 1, by using thin metal (outermost layer) for the spacecraft housing considering the weight limit,
It blocks a certain amount of electron and proton beams from reaching the body.
However, because a shield alone cannot block everything, it is also necessary to block the electron and proton beams that reach the device package inside the housing.
Therefore, choosing devices packaged using high density materials can provide better shielding.
