Industry body SEMI has said that the number of power and compound semiconductor wafer fabs will jump from about 320 in 2019 to more than 330 in 2020.
This count excludes compound semiconductor fabs used to make epitaxial wafers and LEDs. Compound semiconductors such as silicon-carbide and gallium nitride are an important part of power semiconductor growth and there are more than 45 new facilities and lines dut to start production in 2018 or later, SEMI said referencing a report it has produced.

At the same time global installed capacity will increase steadily from about 5.4 million wafer starts per month in 2017 to 6.6 million wafer starts per month in 2021, a compound annual growth rate of about 4 percent.
