Applied Materials produces semiconductor fabrication equipment, including products used in deposition, etching, ion implantation, metrology, wafer inspection and mask-making. Acquisitions expanded AMAT's presence in flat-panel display fabrication equipment and in the solar semiconductor market (since exited). The $4.9 billion Varian acquisition enabled AMAT to build share in high-performance and low-power applications processors.

Applied Materials is the largest semiconductor wafer fabrication equipment, or WFE, manufacturer in the world. Applied Materials has a broad portfolio spanning nearly every corner of the WFE ecosystem. Specifically, Applied Materials holds a market share leadership position in deposition, which entails the layering of new materials on semiconductor wafers. It is more exposed to general-purpose logic chips made at integrated device manufacturers and foundries. It counts the largest chipmakers in the world as customers, including TSMC, Intel, and Samsung.
