MAINEVILLE, Ohio (AP) -- A company that makes silicon wafers for use in cell phones and other electronic devices says it is closing its southwest Ohio plant next year and moving production to other locations, mainly in Arizona and New Mexico.
Arizona-based SUMCO Phoenix Corp. said Tuesday it will stop all operations at its plant north of Cincinnati by July 2010. More than 350 jobs will be lost in Ohio.
Spokeswoman Nancy Norman says the company has been hit hard by the global recession, with many customers moving away from silicon wafers or doing their own manufacturing.
Norman said layoffs will begin sometime after Sept. 1, although some workers may move to other plants.
