Will these advances allow monolithic 3DIC to compete with TSV based 3DIC ? Some say that sequential 3D technology can be much less complex and expensive to implement,...maybe we will be finding out soon.
2013 Semi Award to Xilinx
SEMI has announced that Xilinx is a recipient of the 2013 SEMI Award for North America. The development team at Xilinx was recognized for their commercialization of the silicon interposer “which provides more than two orders of magnitude increase in die-to-die bandwidth per watt. This achievement effectively addressed both challenges of decreasing power and increasing bandwidth for advanced digital ICs. It also decreased latency to only 20 percent for standard input/output connections. Initially announced in 2011 and first shipped in 2012, the incorporation of a silicon interposer, also called 2.5D technology, delivers performance and power requirements dramatically improved compared to standard packaging” Liam Madden accepted the award on behalf of the Xilinx which includes Trevor Bauer, Liam Madden, Kumar Nagarajan, Suresh Ramalingam, Steve Trimberger, and Steve Young.
Semi stated that “Xilinx use of a silicon interposer in their packaging of advanced FPGA represents a major innovation in assembly and packaging technology and provides a learning curve for the many of the technologies that will be needed for high-volume production of 3D-stacked die…. While the elements of redistribution layers on silicon, TSVs, and microbumps were already available [they had not been combined commercially] to provide this high bandwidth, low power packaging solution.”
