A fire burned through the heating and cooling system in a building on the Micron Technology Inc. campus near Boise, sending billows of black smoke into the clear blue morning sky.
The blaze at the semiconductor and solar-panel maker was reported early Monday morning, just after 7 a.m.
It took firefighters from Boise about a half an hour to put out the fire, which broke out in a building that helps support the company's development of solar panels.
Micron says that there were no injuries and that the company doesn't expect any disruptions to its ongoing businesses.
Officials said they were shutting down electricity to the site, to eliminate the potential for problems to spread to high-voltage lines in the area.
Some evacuations of Micron workers were done as a precaution; the cause of the fire is under investigation.
