The use of silicon interposers is growing. Several years ago Xilinx broke new ground by employing interposers in their Virtex®-7 H580T FPGA. Last August Samsung announced what they say is the first DDR4 module to use 3D TSV’s for enterprise servers. Their 64GB double data rate-4 modules will be used for high end computing where … Read More
More news from the 3DASIP conference. Chet Palesko of SavanSys Solution had an interesting presentation with the same title as this blog (although this blog draws from several other presentations too). Chet took a look at what aspects of 3D are likely to get cheaper going forward. He took as a starting point that stuff that is not … Read More
As we move towards packing more and more functionalities and increasing densities of SoCs, the power, thermal and signal integrity issues keep on rising. 3D-IC is a great concept to stack multiple dies on top of each other vertically. While it brings lot of avenues to package dies with multiple functions together, it has challenges… Read More
I think by now there has been good level of discussion on FinFET technology at sub-20 nm process nodes and this is an answer to ultra dense, high performance, low power, and billion+ gate SoC designs within the same area. However, it comes with some of the key challenges with respect to power, noise and reliability of the design. A FinFET… Read More
Last month Cadenceannounced its fastest parasitic extraction tool (minimum 5 times better performance compared to other available tools) which can handle growing design sizes with interconnect explosion, number of parasitics and complexities at advanced process nodes including FinFETs, without impacting accuracy of … Read More
It feels to be at the top of semiconductor technology by having dies with high density of semiconductor design at sub-20nm technology node stacked together into a 3D-IC to form a complete SoC which can accommodate billions of gates. However there are multiple factors to be looked at in order to make that successful amid often conflicting… Read More
3D-IC has a stack of dies connected and packaged together, and therefore needs new testing strategies other than testing a single die. It’s given that a single defective die can render the whole of 3D-IC unusable, so each die in the stack must be completely and perfectly tested before its entry into that stack. Looking at it from a … Read More
At TSMC’s latest earnings call held mid January 2014, an analyst asked TSMC for a revenue forecast for their emerging 2.5/3D product line. C.C. Wei, President and Co-CEO answered: “800 Million Dollars in 2016 ”. TSMC has demonstrated great vision many times before. For me, an enthusiastic supporter of this technology, this statement… Read More
The first keynote at the Burlingame 3D conference was by Doug Yu of TSMC. Not surprisingly he was talking about 3D. In particular, TSMC has WLSI technology that they call CoWoS, which stands for chip-on-wafer-on-substrate which pretty much describes how it is built. This is the technology that Xilinx uses for its recently announced… Read More
I attended the 3D packaging conference in Burlingame this week. The most interesting presentation to me was by Bryan Black of AMD. He argued very convincingly that Moore’s Law is basically over for the PC microprocessor business and the way forward is going to be 3D. AMD are clearly working on all this.
Increased density and… Read More
