By Sara Webb VELDHOVEN, The Netherlands (Reuters) – ASML, the worlds leading provider of tools for making computer chips, gave an upbeat outlook for the first half of this year thanks to strong demand for tablets, smartphones and other consumer gadgets. The Dutch firm, regarded as a barometer for the health of Europes technology sector, beat forecasts for its fourth-quarter results and reiterated its outlook for first-half sales of about 3 billion euros ($4.1 billion). ASML forecast first-quarter sales of around 1.4 billion euros and said it intended to increase its dividend by 15 percent to 0.61 euros per share for 2013. It also said it was on track with the development of its new manufacturing technique which uses EUV, or extreme ultraviolet light, to produce smaller chips.
