Intel appears to be buzzing with excitement over an unexpected yet groundbreaking development in the world of chip design. While discussions in this domain typically revolve around increasing core counts, boosting clock speeds, shrinking transistors, and embracing 3D stacking, the often-overlooked hero of the show has emerged – the package substrate. Intel, currently undergoing a transformation into a foundry company, has unveiled a game-changing innovation in this vital component, and it’s all about glass.

This glass substrate, poised to become a pivotal element in advanced chip designs later in this decade, promises to outshine its organic counterparts in terms of strength and efficiency. Moreover, it opens the door for a more densely packed chiplet and component configuration, a feat fraught with flexing and instability when using traditional organic materials on silicon packages.

In a bold statement, Intel highlights the superior qualities of glass substrates. They can endure higher temperatures, exhibit 50% less pattern distortion, boast an ultra-low flatness that enhances depth of focus for lithography, and offer the dimensional stability crucial for achieving extremely precise layer-to-layer interconnect overlay. With these capabilities in tow, Intel foresees a tenfold surge in interconnect density and the possibility of crafting “ultra-large form-factor packages with very high assembly yields.”

This revelation provides a tantalizing glimpse into the future of Intel’s chips. Two years ago, the company introduced the “gate-all-around” transistor design known as RibbonFET and PowerVia, a technology that enables the relocation of power delivery to the rear of a chip wafer. Simultaneously, Intel announced its intention to manufacture chips for industry giants like Qualcomm and Amazon’s AWS service.

Intel’s glass substrates are poised to make their debut in high-performance domains such as artificial intelligence, graphics, and data centers. This development underscores Intel’s commitment to enhancing its advanced packaging capabilities for its US-based foundries. In contrast, competitors like TSMC face challenges in this realm, with reports suggesting hurdles in their Phoenix, Arizona plant, necessitating the shipment of chip materials back to Taiwan for advanced packaging.

In essence, Intel’s pivot towards glass substrates is a bold step forward in the ever-evolving landscape of chip design. It not only promises technological advancements but also hints at a future where our devices become even more powerful and efficient, all thanks to this unsung hero – the glass substrate.
