The 2017 share was the same level as in 2016 and one point higher than the share the top eight foundries represented in 2015, writes market researcher IC Insights. With the barriers to entry (e.g., fab costs, access to leading edge technology, etc.) into the foundry business being so high and rising, IC Insights expects this 'major' marketshare figure to remain at or near this elevated level in the future.

TSMC, by far, was the leader with USD 32.2 billion in sales in 2017. In fact, TSMC’s 2017 sales were over 5x that of second-ranked GlobalFoundries and more than 10x the sales of the fifth-ranked foundry SMIC.

China-based Huahong Group, which includes Huahong Grace and Shanghai Huali, displayed the highest growth rate of the major foundries last year with an 18% jump. Overall, 2017 was a good year for many of the major foundries with four of the eight registering double-digit sales increases.

Of the eight major foundries, six of them are headquartered in the Asia-Pacific region. As shown, Samsung was the only IDM foundry in the ranking. IBM, a former major IDM foundry, was acquired by GlobalFoundries in mid-2015 while IDM foundries Fujitsu and Intel fell short of the USD 1.0 billion sales threshold last year. Although growing only 4% last year, Samsung easily remained the largest IDM foundry in 2017, with over 5x the foundry sales of Fujitsu, the second-largest IDM foundry.
