Siemens and ASE extend 3D packaging

Technology News |
By Nick Flaherty

Siemens Digital Industries Software is working with volume packaging supplier Advanced Semiconductor Engineering (ASE) on two platforms for multiple complex integrated circuit (IC) package assemblies and interconnects.

The high-density advanced packaging (HDAP) comes from the Siemens OSAT Alliance for 2.5D, 3D IC and Fan-Out wafer-level packaging (FOWLP) technologies and will lead to a single platform for all the advanced packaging technologies. The deal with ASE boosts the 3D chiplet adn FOWLP technology into maistream use.

ASE has developed an assembly design kit (ADK) that helps customers using ASE’s Fan Out Chip on Substrate (FOCoS) and 2.5D Middle End of Line (MEOL) technologies to make use of the full Siemens HDAP design flow. ASE and Siemens have extended their partnership to include the future creation of a single design platform from FOWLP to 2.5D substrate design. All of these use the Xpedition Substrate Integrator software and Calibre 3DSTACK platform that Siemens acquired from Mentor Graphics.

“By adopting the Siemens Xpedition Substrate Integrator and Calibre 3DSTACK technologies, and through integration with the current ASE design flow, we can now leverage this mutually developed flow to significantly reduce 2.5D/3D IC and FOCoS package assembly planning and verification cycle times by about 30 to 50 percent in each design iteration,” said Dr. C.P. Hung, vice president, ASE Group. “Through the comprehensive design flow, we can now more quickly and easily co-design with our customers for 2.5D/3D IC and FOCoS design and close any physical verification issues for their entire wafer package assembly.”

The OSAT Alliance program helps promote the adoption, implementation, and growth of HDAP throughout the semiconductor ecosystem and design chain, enabling system and fabless semiconductor companies to have a friction-free path to emerging packaging technologies. The alliance uses the Siemens HDAP flow 3D packaging for the internet of things (IoT), automotive, 5G network, artificial intelligence (AI) and other fast-growing IC applications.

“We are pleased that ASE continues to develop highly innovative IC packaging solutions as part of our OSAT Alliance,” said AJ Incorvaia, senior vice president and general manager, Electronic Board Systems Division, Siemens Digital Industries Software. “In doing so, and by providing a fully validated ADK for ASE’s leading-edge FOCoS and 2.5D MEOL technologies, we expect to enable customers to more easily transition from classic chip designs to 2.5D, 3D IC, and Fan-Out solutions.”
