The texas blackout was a major factor - it hit an NXP plant that didn't manage to complete an orderly shutdown in time, and caused enough equipment damage that they couldn't get operating again at all for a month, and at reduced capacity for a long time after.

There was also a Samsung plant similarly affected, which I think didn't really get back operational until the end of March.
