Worldwide semiconductor capital spending is projected to grow 2.5 per cent in 2015, to US$66.1 billion.
According to Gartner, this is a down from the 4.1 per cent growth predicted in the previous quarter's forecast.
“Since the previous quarter's forecast, continued weakness in the euro and yen have created major weaknesses in the overall equipment market picture,” says Bob Johnson, research vice president, Gartner.
“With over half of all equipment being produced by either Japanese or European suppliers, the weakness in their currencies has been the primary factor in our reducing our overall outlook for 2015.
“Longer term, we expect modest growth throughout the semiconductor cycle, with just a pause in the equipment market growth expected in 2016, as DRAM goes through a typical cyclical downturn.”
Foundries will continue to outspend the logic integrated device manufacturers (IDMs) in 2015.
Worldwide foundry spending is forecast to increase 17.2 per cent, in contrast with the 1.4 per cent decline in total logic spending.
However, the longer-term outlook for total logic spending is strong as predicted mobility market saturation will dampen the need for new capacity and create an environment where existing capacity is upgraded to the latest node.
Worldwide memory capital spending remains strong for 2015, with a 3.2 per cent increase anticipated, compared with a 10.2 per cent increase in the previous quarter's forecast.
The reduction from the previous forecast is a result of spending announcements by major manufacturers, which were lower than previously anticipated, and reflected the fact that major equipment types are cheaper due to weaknesses in exchange rates.
Memory manufacturers currently enjoy a strong chip-pricing environment, which sets the stage for continued spending growth through 2015.
However, an anticipated oversupply in DRAM in 2016 will lead to a 13.6 per cent decrease for worldwide memory spending next year.
Wafer-level equipment spending is forecast to increase 0.1 per cent in 2015, as manufacturers pull back on new fab construction and concentrate instead on ramping up new capacity.
“As we get better visibility into individual company spending plans for 2015, it is apparent that caution is a prevailing sentiment, with the exception of memory, where manufacturers are adding capacity in response to favourable market conditions,” Johnson adds.
