(October 6, 2010) — CEA-Leti and SPP Process Technology Systems (SPTS) have agreed to develop advanced 300mm through-silicon via (TSV) 3D IC processes at CEA-Leti’s 300mm facilities in Grenoble, France. The agreement defines their collaboration on a range of 3D TSV processes to optimize etch and deposition technologies used to create next-generation high aspect ratio TSVs.
The partners will research alternative hardware and processes to address the need for new methods of cost-effective via fill. In some via-middle applications, where the via is created between contact and first back-end-of-line (BEOL) metal layer, via aspect ratios may extend beyond 10:1, and these very high aspect ratios require a new approach to current etch and deposition techniques.
"3D-IC technology plays a key role in enabling cost-effective performance for the entire micro-electronics industry. Whether for nomadic devices, data centers, MEMS or optical devices, 3D-ICs form the basis of building cost-effective, high performance chips with multiple functionalities. Combining Leti’s advanced research and development knowledge with the technical expertise from an equipment manufacturer with proven production capabilities will cover the complete range of Copper-based TSV processes," said Dr. Laurent Malier, CEO of CEA-Leti. SPTS is encouraged by the possibilities in this joint equipment-and-process development with CEA-LETI, added Kevin Crofton, managing director, SPTS UK Division, and executive vice president, SPTS. “Our etch, physical vapor deposition (PVD) and chemical vapor deposition (CVD) systems are acknowledged technology leaders in the field of TSVs. Leti and SPTS understand the importance and value of creating an optimized TSV solution, and both acknowledge that it is most effective when the wafer-processing-technology and device experts are working together on integrated process flows.”
TSV technology is quickly gaining industry prominence as this method of 3D integration facilitates a thinner interconnect layer between stacked devices, allowing higher density interconnectivity to produce better electrical performance, all resulting in increased functionality and cost-efficiencies, say the partners.
