Integrated Device Technology, a San Jose, Calif. -based chipmaker, is cutting the workforce of the former Tundra Semiconductors in Kanata, Ottawa. The Ottawa Citizen is reporting the layoffs of about 20 employees. The cuts come on the heels of a management shakeup in the wake of weaker sales and a return to losses. IntegratedDeviceTechnologyIDTIDT acquired Tundra Semiconductors in 2009. According to the paper, IDT inherited 135 employees at the location and cut the operation to about 75 employees before undertaking some rebuilding as sales improved. IDT hasn’t responded to questions about the Ottawa layoffs. However, in a regulatory filing, the company said that 90 employees, about 5 percent of the company’s entire workforce, had left. According to sources, the layoffs included some senior employees in fast-growing products. Previously, IDT shut a separate Ottawa operation before it bought Tundra for $121 million. People familiar with the operation say the Ottawa location supports key products that are now growing, and new hiring might happen if financials improve.
