Through three quarters of calendar year 2017, market shares of top semiconductor equipment manufacturers indicate large gains by Tokyo Electron and Lam Research, according to the report “Global Semiconductor Equipment: Markets, Market Shares, Market Forecasts,” recently published by The Information Network, a New Tripoli-based market research company. The chart below shows shares for the entire year of 2016 and for the first three quarters of 2017. Market shares are for equipment only, excluding service and spare parts, and have been converted for revenues of foreign companies to U.S. dollars on a quarterly exchange rate.
