Semiconductor plants – perhaps five of them – were ordered shut down, in Texas, due to the state’s failed electricity grid.
Semiconductors are manufactured in a chemical engineering process that can take weeks, per chip, along the line. The time required depends on the components being manufactured and can range from weeks to two months.
Thus, shutting down these lines could disrupt service for some time.

There is already a global electronic components shortage that has caused most all major auto manufacturers to temporarily close or slow down auto manufacturing. This shortage is compounded by a multi-day fire at AKM Semiconductor in Japan, last fall. That firm made up to 90% of the world’s components for consumer electronics, plus Bluetooth chips and other items and was expected to cause at least six month delays in parts shipments.
I an electronic item I ordered last October has been postponed indefinitely – a key part was made by AKM. Another item I ordered in January, with expected shipment of Feb 12, was delayed until June 21, 2021.
