Contract-based chip prices are likely to rise around 15 percent to 20 percent, depending upon the level of sophistication, people familiar with the matter said. Photo: ReutersSamsung’s decision is a shift from last year’s relatively stable pricing policy, when the industry rushed to raise prices in the wake of a global chip shortage. Samsung and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) account for more than two-thirds of global capacity for outsourced chips. Contract chip manufacturers including TSMC and United Microelectronics Corp (UMC, 聯電) are telling clients that they plan to raise prices by a mid-to-high single-digit percentage, on the heels of a price hike several months ago. Industry leader TSMC has told clients that it plans to raise prices by about 5 percent to 8 percent next year, following a 20 percent price hike last year, the Nikkei said.
