Microsemi Set to Shutter Colorado Plant After Delays

Irvine’s Microsemi Corp., which makes chips for industrial uses by the military, is finally wrapping up a plant closure in Colorado that has been hung up for years.

Back in 2005, Microsemi announced it was set shutter its plant in Broomfield, Colo., as part of a cost cutting plan.

The original date of closure was slated for mid-2006.

Microsemi disclosed in a government filing Tuesday that the Broomfield site is expected to close next year.

The 130,000-square-foot factory at one point had some 165 workers and made up 12% of Microsemi’s yearly sales.

This year it had about 70 workers and made up about 4% of yearly sales.

The Colorado plant has given the company some headaches over the years.

The closure and eventual sale of the plant has been delayed by a long-running dispute with a local business owner next to the plant. The person claimed chemicals from the plant contaminated his property.

Microsemi has closed about 10 plants in the past 8 years.

It’s one of the few chip companies in Orange County that actually manufactures chips here at a plant in Garden Grove.

Microsemi had a recent market value of about $1.5 billion.
