ALBANY & SAN JOSE, USA: Olympus Integrated Technologies America Inc. (Olympus-ITA), a subsidiary of Olympus Corporation of the Americas and a leader in advanced inspection and defect review systems, announced that it has provided an infrared (IR) inspection and defect review system with metrology software to SEMATECH, the global consortium of semiconductor manufacturers, for its 3D R&D Center at the College of Nanoscale Science and Engineering’s (CNSE) Albany NanoTech Complex.
The system enables SEMATECH to verify alignment of bonded wafers and through silicon vias (TSV). SEMATECH’s 3D program was established to deliver robust 300mm equipment and process technology solutions for high-volume TSV manufacturing.
The SEMATECH 3D interconnect process using TSVs requires bonding the active side of processed wafers together. Once the wafers are bonded there is an immediate need to verify the accuracy of the bonding alignment, but the active wafer surfaces containing the alignment targets are no longer visible.
The Olympus IR Inspection System allows observation and image acquisition of the alignment targets and vias by “seeing” through the 775µm thick silicon wafer to the patterned surfaces. Overlaid alignment marks are imaged and measured to verify bonding alignment accuracy. Alignment is critical for the device to function optimally. The Olympus tool was installed and accepted in April, 2009.
“Precise alignment is one of the major challenges affecting the performance of the 3D interconnects,” said Sitaram Arkalgud, SEMATECH’s director of 3D Interconnect. “Wafer bonding is a key process, and Olympus’ defect review system provides precise imaging technology that allows our researchers to address the technical challenges related to bonding interface defectivity and overlay metrology.”
“We have been collaborating with SEMATECH on inspection and defect review tools since 2001 and working with the 3D group since last year to provide a method to image and measure overlay offsets after wafers have been bonded together,” said Olympus-ITA president Greg Baker. “Olympus’ IR inspection and defect review tool with metrology functionality is now in operation at SEMATECH’s 3D R&D Center and is proving to provide very clear images and accurate measurements to help ensure via alignment and interconnectivity.”
“The SEMATECH-CNSE partnership continues to enable innovative process solutions for the manufacturing of advanced nanoscale devices,” said Richard Brilla, CNSE vice president for Strategy, Alliances and Consortia. “The addition of the Olympus IR inspection and defect review system will support that effort, while further enhancing the world-class technological capabilities of CNSE’s Albany NanoTech Complex for the benefit of our global corporate partners and the nanoelectronics industry.”
Olympus-ITA will be participating in the SEMATECH Workshop on 3D Interconnect Metrology, being held on July 15, 2009 at the San Francisco Marriott in San Francisco, CA. Richard Poplawski, on-site project manager for Olympus-ITA, will give a presentation titled 3D Interconnect Bonded Wafer Pair Metrology Using IR Microscopy.
The purpose of the workshop is to gain a better understanding of how new and existing wafer metrology technologies can be utilized, modified, or enhanced to measure and improve 3D interconnect processes.

How 3-D integration will challenge and reshape memory industry
LYON, FRANCE: The memory semiconductor industry is about to go through a period of major technological changes as new integration trends and disruptive packaging technologies pave the way to the future growth of this industry.
Memory Applications: Packaging & Integration Trends, a new 2009 Report from Yole Développement, presents the end applications driving the use of 3-D integrated memories and their key players. It also includes an overview of the memory packaging market, its forecasted evolutions with new applications and growth in Flash and DRAM market.
Historically, DRAM memory market has been mostly driven by computing applications, while NOR Flash has been mainly deployed into consumer and communication devices. More recently, NAND Flash memory has emerged as the most promising solid state storage solution for current consumer devices and is showing as the best candidate for hard disk drive replacement in the near future.
Integration is the next challenge
On the other hand, today wireless is growing and enabling new market segments everywhere, (smartphones, mobile pocket computing devices…). As a result, CONNECTIVIY and INTEGRATION are now new drivers to deal with.
Demand for data is increasing everywhere: Faster pipes, more pipes (WAN, LAN, PAN), HD multimedia! Current complexity and concurrency require more than ever higher data capacity, improved power consumption and is stressing existing well established architectures: new interconnects, integration schemes and packaging technologies are needed to support higher performance, breakthrough density and low power consumption devices. 3-D IC integration is showing as a major solution path to tackle these challenges and memories will be key components in achieving this successful integration.
3-D integration will open a new application space for memory market growth
Yole Developpement has followed the burgeoning 3-D Packaging industry since its early beginning. The global economic downturn is challenging the fast adoption of the “Through Silicon Vias” technology into high volume applications such as low cost memories. “However, we are seeing concrete signs that this market is definitely taking-off, with the first 3-D integrated DRAM memories being shipped this year: we estimate that about 20 000 wafers of DRAM memory will be shipped with 3D TSV by the end of 2009, with production moving forward to higher volumes in 2010” explained Jérôme Baron, Technology & Market Analyst at Yole Développement.
By 2013, Yole Développement expects that telecom and computing industries will drive more than 70% percent of the total volume for 3-D TSV stacked memories.
3-D integration with memories is a hot topic at the moment because of the challenging market conditions and of the important investment needed for building the required infrastructure. As a result, pre-competitive alliances and partnerships may be necessary to drive the risk down while accelerating product adoption. Memory manufacturers, CMOS foundries, OSAT packaging houses, Fab-less IC players and integrated device manufacturers are all concerned and actively preparing for this ultimate integration.

This new study aims at answering the following questions: What are the end applications driving the use of 3-D integrated memories in the Flash and DRAM market? Who are the key players doing it? How will it happen? When will the market ramp up? What is the impact of the current economic turmoil application per application? Finally, how big is this 3-D memory market going to be and at which conditions in terms of cost?
Memory applications key market metrics
To support its investigations in this complex and fast moving market, Yole Development is also distributing the “Memory LSI – 2008 Report” from Nikkei BP Consulting, a market research company based in Tokyo, Japan that has been focusing on the analysis of the key market metrics of the memory industry, based on strong interactions all the year with memory fabs worldwide. The two complementary reports are available separately or both in a bundle package.
