SUMCO, a Japanese silicon wafer manufacturer, which it says caters for two thirds of the world’s wafer market, is reporting a 20% increase in the price of silicon wafers compared with the same time last year. That’s not all; they’re also looking to raise the price by another 20% next year, and by an undisclosed amount in 2019, too. Memory industries are continuing to announce their plans for extending their production facilities. SUMCO is estimating that the global demand in 2020 will be 6.6 million units per month. On the other hand, silicon wafer industries are limiting themselves from making extensions of their facilities, as the price of silicon wafer can fall once they increase their amount of supplies.
