Being a tech guy ill explain what is happening here, for the past few years the two major wafer factories the TWO major ones are SAMSUNG and TSMC who produce most of the chips for cars, graphics ect ect, the other 3 micron, sk hynix and kioxia/WD (kioxia is toshiba rembranded to seperate the companies) the last 3 manufacture memory wafers, the main two manufacture wafers for car computer, tv computers, computer parts etc etc, these wafers then get turned into chips etc.
Before the Pandemic their schedule was pretty much 10 months on months off for maintenance, they are also both building new plants as well which requires more wafer than a probably a whole quarter of car orders, so when we had the 1st lockdown globally the car brands and sales were hit naturally, this meant car companies had over ordered (in the computer industry they thought people would by less as they were not working) Then when we had the second global wave the car manufacture in all their wisdom seemed to think well lets not order as much chips, which then means the chip brands order less wafers as no one in likes to hold stock.
but suddenly people were buying cars, they did not want to travel on public transport etc, so they wanted more chips… the trouble was the factory had already sold the wafer making time (almost like an allocation to chip makers for laptops etc who were seeing a massive uptern in sales) they also decided with the other time that they would make the left over time to do wafers for their new factories.
The result is no time for car chip wafers and no time for high end computer product wafers either, they were fully booked and working around the clock with crazy demands.
