Package-level reliability success is a significant milestone towards the prove-out of a full-scale 3DIC solution for customers
Hsinchu, Taiwan, January 29, 2013 âSTATS ChipPAC Ltd. (SGX-ST: STATSChP), a leading semiconductor advanced packaging and test service provider, and United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) ("UMC"), a leading global semiconductor foundry, today announced the worldâs first demonstration of TSV-enabled 3D IC chip stacking technology developed under an open ecosystem collaboration. The 3D chip stack, consisting of a Wide I/O memory test chip stacked upon a TSV-embedded 28nm processor test chip, successfully reached a major milestone on package-level reliability assessment. This success demonstrates a total solution for reliable 3D IC manufacturing through the combination of UMCâs foundry and STATS ChipPACâs packaging services.
âThe next level of chip integration is rapidly evolving, and 3D IC technology is poised to enable the next frontier of IC capabilities for customers under various deployment models.â said Shim Il Kwon, VP of Technology Innovation of STATS ChipPAC, âThe open ecosystem collaborative approach drives proven and reliable 3D IC solutions for the semiconductor market by combining the foundry partnerâs robust, leading-edge TSV and front-end-of-line (FEOL) process technologies in a complementary platform with an Outsourced Semiconductor Assembly and Test (OSAT) service provider with innovative engineering excellence to seamlessly integrate mid-end-of-line (MEOL) and back-end-of-line (BEOL) 3D IC processes. We are pleased with UMCâs commitment to this role and look forward to future collaborations. The results are a proven solution platform that will enable customers to capitalize on new market opportunities.â
S.C. Chien, vice president of Advanced Technology Development at UMC, said, âWe see no imperative to restrict 3D IC to a captive business model, as UMCâs development work with nearly all the major OSAT partners for 3D IC has been very productive. Our successful collaboration with a leading OSAT partner like STATS ChipPAC has further established the viability of an open ecosystem approach. This model should work especially well for our mutual 3D IC customers, as foundry and OSAT can utilize their respective core strengths during development and delivery, while customers can benefit from keeping supply chain management flexible and realize better transparency over technology access compared to closed, captive 3D IC business models.â
UMC and STATS ChipPACâs proven open ecosystem 3D IC approach sets an important standard for collaboration within the industry supply chain to achieve mutual success. Under the 3DIC open development project with STATS ChipPAC, UMC provides the FEOL wafer manufacturing, with a foundry grade fine pitch, high density TSV process that can be seamlessly integrated with UMCâs 28nm poly SiON process flow. The know-how developed will be applied towards implementation on the foundryâs 28nm High-K/metal gate process. For MEOL and BEOL, STATS ChipPAC performs the wafer thinning, wafer backside integration, fine pitch copper pillar bump and precision chip-to-chip 3D stacking.
