2 Min Read (Reuters) - Analog Devices Inc is delaying the closure of a California chip factory as sales boom and supplies remain tight, the company’s chief executive told Reuters after the company reported better-than-expected quarterly results. ADI previously said it would close its semiconductor factory in Milpitas, California, which makes chips for the automotive industry, sometime before the company’s fiscal year ends in October. In December, ADI told California regulators the plant’s 255 employees would be laid off by Feb. 19. But ADI Chief Executive Officer Vincent Roche on Wednesday said the plant will stay open longer due to tight supplies that could persist through October.
