3D packaging disrupts the IC supply chain — ConFab session dedicated to the OSAT/foundry/fabless relationship

May 13, 2011The ConFab gathers semiconductor industry leaders to discuss the biggest trends in the chip manufacturing sector. One of these major trends is 3D packaging. In Session 2 on Monday (May 16), John Waite (GLOBALFOUNDRIES), Raj Pendse (STATS ChipPAC), Robert Darveaux (Amkor), and Nick Yu (Qualcomm) will combine fabless, foundry, and packaging house perspectives on the disruptive design and process changes that 3D creates for the semiconductor and packaging industries.

John Chen (Nvidia), Jeong-ki Min (Samsung Electronics), and Abraham Yee (Nvidia) will lead "Collaboration to Strengthen the IC Supply Chain."

Smaller dimensions and higher complexity chips are driving "More Moore," while "More than Moore" is pushing vertical integration, such as 3D TSV. Both require changes to the traditional frontend and backend of semiconductor manufacturing.

3D packaging, whether bonded wafers with through silicon vias (TSV) or wire bonded chip stacks, push packaging processes into the fab, and make wafer-level processes the outsourced semiconductor assembly and test (OSAT) provider’s responsibility. In this new supply chain, many questions are raised about ownership and responsibility in the implementation of a new chip design. Since our IC industry has long been divided into EDA or fab tool supplier, fabless, foundry and assembly/test companies, getting everyone to work together and make profits for each party can be extremely challenging. This session is intended to explore various options.

Session 2, "Collaboration to Strengthen the IC Supply Chain" presentations:

John Waite, VP, packaging development & central engineering, GLOBALFOUNDRIES: Waite will present "Supply Chain Reaction: A Collaborative Approach to Packaging Innovation." As the industry moves aggressively to more advanced technology nodes, the once "bland" interconnect, assembly and packaging processes can now improve performance and power efficiency as well as reduce costs for chip designers. Chip-package interaction (CPI) is significantly more complex today, requiring coordination between design and manufacturing. It is increasingly difficult for foundries and OSATs to be able to deliver end-to-end solutions that meet the requirements of leading-edge designs. A new approach is needed — one that leverages the success of a "shared investment, shared return" model.

Raj Pendse, VP product & technology marketing, STATS ChipPAC: Pendse will present "3D Packaging Evolution from an OSAT Perspective," illustrating the synergies and intersections among packaging technologies (i.e. traditional die and package stacking on substrates, fan-in and fan-out wafer level packaging and 3D Si integration) and the resulting future path for packaging technology. Pendse will discuss the transformed role of the OSAT industry in supporting this evolution. Latest developments in wafer thinning, micro bumping, micro bonding and logical hand off points among Si and package foundries will be presented, and Pendse will look at "bridge" technologies — interposers, TSV substrates — that play an interim role in the commercialization of 3D.

Robert Darveaux, CTO, Amkor: Darveaux will present "Supply Chain Challenges for 3D Integration of Memory and Logic Devices using TSVs." While package-on-package (POP) technology allows ease of test, flexible sourcing, and mature interconnect technology, TSV technology suffers from difficult-to-test high-density area array contact pads or bumps; bare or partially assembled memory and logic die that are difficult to burn in adequately; a newer joining technology not widely available to OEMs and contract assemblers; a poorly characterized joining process yield; and ultimately unclear ownership of defect liability. These problems can not be resolved by technologies or business models alone.

Nick Yu, VP of technology development, Qualcomm: Yu is presenting "3D Through Si Stacking Technology – a Qualcomm Perspective." Qualcomm, as an integrated fabless company, has several primary motivations for following 3D TSV-based stacking technologies. Yu will propose a roadmap for the evolution of the 3D technology, and detail the integration challenges for an integrated fabless manufacturer using a distributed supply chain. Yu shares Qualcomm’s implementation strategy, and points to some of the gaps in the business model associated with 3D products.
