** European semiconductor stocks fall sharply, tracking Samsung Electronics 005930.KS shares decline, as worries over AI data centre rollout overshadow the South Korean memory-chip maker's 19-fold jump in operating profit 

    ** STOXX 600 Tech sub-index .SX8P slips 1.8%, the biggest decliner among STOXX sub-indices
  
** Samsung's strong earnings had been largely priced in after a steep share-price rally, while investors remain concerned about slower AI infrastructure spending by major U.S. technology firms, Petra Capital Management's Albert Young says
** Dutch semiconductor companies ASML ASML.AS, ASM International ASMI.AS and BE Semiconductor BESI.AS fall 3.8%-3.9%, while Germany's Infineon IFXGn.DE and Aixtron AIXGn.DE decline about 4.3%
** France's STMicroelectronics STMPA.PA slips 4.2%
** Smaller peers are also under pressure, with Soitec SOIT.PA down 12.5%, Siltronic WAFGn.DE losing 7.4%, X-Fab XFAB.PA off 3.2% and AMS-Osram AMS2.VI down 4.1%
