This collaboration is set to enable the realization of next-generation high-performance and complex SoC designs, with a strong focus on advancing opto-electronic devices that integrate silicon photonics.

Technical / Clinical Details

Adoption of Intel 18A-P Process: The 18A-P is one of Intel’s most advanced process technologies, featuring innovative elements such as the Gate-All-Around (GAA) transistor structure ‘RibbonFET’ (succeeding FinFET) and the ‘PowerVia’ backside power delivery network. These technologies promise high transistor density and superior power efficiency.
Expansion of SoC Roadmap: By leveraging the 18A-P process, Socionext plans to design and develop SoCs for more demanding applications, including AI accelerators, data center processors, and high-performance networking chips, thereby extending its market reach and technological capabilities.
Enabling Opto-Electronic Device Integration: The high integration density and power efficiency offered by the 18A-P process are critical for realizing next-generation opto-electronic devices, such as co-packaged optics (CPO), where silicon photonics are directly integrated into SoCs. This tight coupling of electrical and optical signal processing will resolve data transfer bottlenecks and boost overall system performance.

Background & Context

The proliferation of AI and High-Performance Computing (HPC) demands unprecedented levels of performance and efficiency from semiconductor chips. Traditional electrical interconnects are increasingly becoming a data transfer bottleneck, making the integration of optical technologies an imperative. For SoC design companies like Socionext to adopt state-of-the-art foundry processes from Intel is a common strategy to share development costs and risks while rapidly bringing advanced technologies to market. This collaboration underscores the acceleration of technological innovation in the semiconductor industry and the potential for new SoCs through heterogeneous integration.

Strategic Significance & Outlook

Socionext’s adoption of the Intel 18A-P process significantly increases the likelihood of innovative opto-electronic devices emerging across diverse sectors, including data centers, 5G/6G communication, autonomous vehicles, and edge AI devices. Specifically, the ability to directly integrate silicon photonics into high-performance SoCs will dramatically improve the power efficiency and bandwidth of AI accelerators and high-speed networking equipment. This advancement will contribute to reducing data center power consumption, accelerating AI inference and training speeds, and fostering the wider adoption of optical communication technologies, marking a crucial milestone in building next-generation digital infrastructure.
