Chip-to-Wafer direct-metallic-bonding technology developed at Leti used in customized 300mm device bonder
CEA-Leti partnering with SET, STMicroelectronics, ALES and CNRS-CEMES on advanced chip-to-wafer technologies for 3D integration.
CEA-Leti today announced a multi-partner project to demonstrate high-alignment-accuracy (<1µm) chip-to-wafer structures made by direct metallic bonding. Such structures are required for high-performance 3D integrated circuits and could enable a wide range of applications in microelectronics as well as in optoelectronics or MEMS.
The customized system will be used by the Minalogic PROCEED project. Minalogic is the global competitive cluster specialized in micro- and nanotechnologies and embedded intelligence. In addition to Leti and SET, partners are STMicroelectronics, ALES and the CNRS-CEMES. The PROCEED Minalogic project is a 4.2 million-euro, 24-month project that began in December 2009 and is supported by French FIU (Fond Interministeriel Unique).
“This collaboration puts Leti in a very good worldwide position for 3D-technologies development,” said Leti CEO Laurent Malier. “We will identify the key challenges of 3D product engineering, and chip-to-wafer strategy with direct-metallic bonding is a very promising option for overcoming those challenges.”
“SET is proud to be leading the Minalogic project, PROCEED, in collaboration with STMicroelectronics, CEA-Leti, ALES and the CNRS-CEMES,” said Gaël Schmidt, managing director of SET. “It provides cutting-edge equipment solutions enabling the CEA-Leti process integration. SET has a strong interest for this non-thermocompression metal-to-metal bonding, which may be a key to throughput improvement required for the adoption of 3D-IC integration.”
CEA is a French research and technology organization, with activities in four main areas: energy, information technologies, healthcare technologies and defence and security. Within CEA, the Laboratory for Electronics & Information Technology (CEA-Leti) works with companies in order to increase their competitiveness through technological innovation and transfers. CEA-Leti is focused on micro and nanotechnologies and their applications, from wireless devices and systems, to biology and healthcare or photonics. Nanoelectronics and microsystems (MEMS) are at the core of its activities. As a major player in MINATEC campus, CEA-Leti operates 8,000-m² state-of-the-art clean rooms, on 24/7 mode, on 200mm and 300mm wafer standards. With 1,200 employees, CEA-Leti trains more than 190 Ph.D. students and hosts 200 assignees from partner companies. Strongly committed to the creation of value for the industry, CEA-Leti puts a strong emphasis on intellectual property and owns more than 1,700 patent families.
