Atomic tuning on cobalt enables an eightfold increase of hydrogen peroxide production

Just like we take a shower to wash away all the dirt and other particles, semiconductors also require a cleaning process. However, its cleaning goes extreme to make even trace contaminants "leave no trace." After all the chip fabrication materials are applied to a silicon wafer, a strict cleaning process is taken to remove residual particles. If this high-purity cleaning and particle-removal step goes wrong, the electrical connections in the chip are likely to suffer from it. With ever-miniaturized gadgets on the market, the purity standards of the electronics industry reach to a level, like finding a needle in a desert.
