AXT

AXT, Inc. engages in the design, development, manufacture and distribution of compound and single element semiconductor substrates. The company is headquartered in Fremont, California and currently employs 1,383 full-time employees. Its wafer substrates are used when a typical silicon wafer substrate cannot meet the performance requirements of a semiconductor or optoelectronic device. The company has two product lines: specialty material substrates and raw materials integral to these substrates. Its InP is a semiconductor wafer substrate used in broadband and fiber optic applications, 5G infrastructure and data center connectivity. Its semi-conducting GaAs substrates are used to create opto-electronic products, including high brightness light emitting diodes that are often used to backlight wireless handsets and LCD televisions and for automotive, signage, and lighting applications. Its Ge substrates are used in applications, such as solar cells for space and terrestrial photovoltaic applications.
