One of the key commentaries about the current semiconductor shortages is around where exactly the bottlenecks are. The traditional interpretation of a semiconductor shortage implies that not enough silicon can be made, but over the last few months a number of companies have pointed to post-silicon production, such as testing and packaging, causing some of the issues. To the best of our knowledge, none of the companies affected by the shortages are specifically pointing at partner companies or specific supply chain areas where there is a bottleneck, however there have been a number of comments focused in the direction of packaging, substrates, and the specialist films involved for high performance compute.
