We understand the importance of selecting the proper packaging solution to meet the technical and cost constraints of each design. Our packaging capabilities include 2.5D technology, and OpenFive’s extensive experience enables us to meet the unique needs of each customer and successfully launch their product.
What is 2.5D technology
2.5D IC is a packaging technology where multiple die are placed face down and side by side on a silicon or organic interposer. The active surface of the die has micro-bumps that connect to pads on the surface of the silicon interposer. Connections from these pads directly connect to TSVs (Through Silicon Vias), which pass through the interposer substrate and connect to the package substrate. The connections from the pads can also be connected through interposer routing to other TSVs that are in-turn connected to pads and micro-bumps of other die on the interposer. 2.5D IC technology helps reduce interconnection length between multiple dies assembled on the interposer, leading to lower power consumption and lower latency as well as an increase in the number of interconnection routes on the interposer, which results in increased bandwidth compared to traditional 2D off-chip interconnections.
The picture above shows mounting 2 or more silicon dies onto an interposer die and then assembling the whole system into a single package.
Silicon based on 2.5D technology is making inroads into high performance computing, graphic processors, and AI (Artificial Intelligence) processors utilizing High Bandwidth Memories (HBM). These HBMs are available as tested KGDs (Known Good Die), and are mounted on the interposer along with die containing the main processor and HBM controller. High density routing through the interposer interconnects the two die.
The main advantages of this technology are miniaturization, enhanced performance, lower latency, increased bandwidth and power efficiency. Key advantage of 2.5D technology is that the die that are mounted on interposer need not utilize the same process node or technology. This helps in using die manufactured in various technology nodes. As an example, a HBM 3D stacked memory die can be mounted on the interposer with a processor die manufactured in 7nm process technology.
