EV Group's Innovative GEMINI® Wafer Bonding System

In the fast-evolving world of semiconductor manufacturing, staying ahead of technological advancements is essential. EV Group (EVG), a prominent player in innovative process solutions, has introduced its latest development in wafer bonding technology: the next-generation GEMINI® automated production wafer bonding system tailored for 300-mm wafers. This system is set to revolutionize the MEMS (Micro-Electro-Mechanical Systems) manufacturing landscape.

Key Features and Innovations

The newly designed GEMINI® platform incorporates a high-force bond chamber that significantly improves bond quality and yield over larger wafer surfaces. This innovation is crucial as the MEMS market is projected to experience substantial growth, increasing from approximately USD 14.6 billion in 2023 to an estimated USD 20 billion by 2029, driven mainly by advancements in inertial sensors, microphones, and microspeakers utilized in wearable devices such as smartwatches and earbuds.

EVG’s system has been developed specifically to address the challenges associated with scaling from 200-mm to 300-mm production lines. As manufacturers transition, they encounter the need for higher bond forces to maintain adequate pressure across the increased surface area of larger wafers. The new GEMINI® system is engineered to exceed these requirements, ensuring not only compliance with current manufacturing demands but also adaptability for future developments in MEMS technology.

Enhanced Bonding Capabilities

With the GEMINI® platform, users can expect a fully integrated modular system that supports a wide range of bonding processes. Featuring up to four bond chambers, the system offers adjustable bond forces that can reach up to 350 kN, alongside a high vacuum capability that descends to 5 x 10-6 mbar. Moreover, it provides overpressure capacity of up to 2000 mbar absolute, making it one of the most advanced systems currently available in the market.

In addition to its robust technical specifications, the GEMINI® system inherits key functionalities from its predecessor, such as automated optical alignment and customizable module configurations. These features provide users with the flexibility required to optimize their wafer bonding processes for a variety of MEMS applications.

Addressing Market Needs

Dr. Thomas Glinsner, the corporate technology director at EV Group, commented on the strategic importance of the GEMINI® system, stating, "EVG has over 30 years of experience in providing production wafer bonding systems tailored for the MEMS industry. Our ability to foresee market trends and technological shifts allows us to deliver solutions that not only meet but anticipate customer needs. The next-generation GEMINI® system is a testament to this vision, facilitating the development of next-generation MEMS devices and products."

As the MEMS industry continues to evolve, manufacturers are increasingly focused on how to meet rising demand while ensuring efficiency and product quality. The GEMINI® system is positioned to play a pivotal role in ensuring that manufacturers can produce innovative MEMS devices, equipped for the challenges of tomorrow.
