Chip machinery maker ASML expects to book higher turnover than expected this year, because the demand for smartphones and tablets is picking up.

ASML said in a statement it expects full year sales to reach €5bn, compared with €4.7bn in 2012. The company said earlier it expected turnover would be flat.

ASML booked an 8% increase in net profit in the second quarter of this year, compared with the year earlier period.

Net profit reached €239m as demand for 4G – fast mobile internet – increased. ASML sold 25 new chip machines in the first quarter and 34 in the second.

Last year, ASML signed a €2bn development and investment deal with its main customers, including Samsung, Intel and TSMC.
