About Nexx Systems

Nexx Systems Inc., founded in 2001 and headquartered in Billerica, Massachusetts, operates as a specialized provider of processing equipment for the semiconductor manufacturing industry. The company focuses on the advanced wafer-level packaging (WLP) market, which is crucial for producing smaller, thinner, and more powerful electronic devices.

The firm's core business involves the design and provision of advanced deposition systems, including electrochemical deposition (ECD), physical vapor deposition (PVD), and plasma cleaning systems. These products are integral to processes such as wafer bumping, copper pillar formation, and redistribution layers (RDL), which are essential for creating the interconnects that link a semiconductor die to external circuits. Nexx Systems serves a global clientele of semiconductor manufacturers and outsourced semiconductor assembly and test providers (OSATs), particularly in Asia where high-volume production is critical. The business model leverages an outsourced manufacturing strategy to minimize fixed costs and enhance scalability, allowing the company to focus on system design, quality control, and technology leadership.

A significant milestone in the company's history was its acquisition by Tokyo Electron Limited (TEL) in March 2012 for $206 million. This acquisition was a strategic move for TEL to gain an immediate foothold in the back-end packaging sector and integrate Nexx's deposition technologies into its broader product portfolio. Following the acquisition, Nexx Systems was renamed TEL NEXX, Inc. and operated as a wholly-owned subsidiary. Later, in October 2018, ASM Pacific Technology Ltd. (ASMPT) acquired TEL NEXX from Tokyo Electron, further expanding its own offerings in the advanced packaging market. This series of acquisitions underscores the value of Nexx's specialized technology within the semiconductor industry.
