Description

<p>Many radiation particles, such as electrons, protons and heavy ions, exist in space. The semiconductor devices installed in space applications, such as artificial satellites, exhibit destructive and nondestructive malfunctions owing to such radiation particles. The effects of a total ionizing dose, single event and displacement damage are known as three major effects of radiation on semiconductor devices. In this article, the response of triple junction (3J) solar cells to radiation is introduced as one of the examples of the displacement damage effects. The degradation mechanism of 3J solar cells is also discussed. As an example of single event effects, the single event transient observed for logic LSIs is introduced, which is one of the current major issues in logic LSIs for not only space but also terrestrial applications.</p>
