FRANKFURT (Reuters) - China's top state silicon chipmaker has further raised its stake in Dialog Semiconductor, buying into share price weakness triggered by fears the Anglo-German firm could lose its top customer Apple Inc (NASDAQ:AAPL).
Tsinghua Unigroup, through two wholly owned units, controls an 8.15 percent voting stake, Frankfurt-listed Dialog said in a regulatory filing on Thursday. That is up a percentage point since the last disclosure by Dialog on Tuesday.
