News Government Survey: Semiconductor Fab Capacity Still a Huge Issue

Some companies still have fabs over 1000nm for high-voltage/current/power electronics like audio amplifiers, PWM regulators with integrated switches, industrial drivers/receivers, protection circuitry, etc.
 
And 2N3055 is still produced till now 😊
Ancient jellybeans parts like this will likely still get made 30+ years from now simply because there are countless applications that still won't require anything better than that and lots of critical equipment requiring unconditional maintainability even under near-apocalyptic conditions will keep using them too.
