PanelSemi, a developer of ultra-thin flexible LED displays and semiconductor substrates, has partnered with NGK Insulators to create high-performance hybrid packaging solutions. Leveraging its tiled thin-film transistor (TFT) circuit fabrication technology, PanelSemi is developing a hybrid circuit board that combines fine wiring and functional circuits on polyimide film with a ceramic substrate. The company is expanding into high-performance circuit boards for semiconductor modules, targeting large-scale panel manufacturing for wireless communications and opto-electronic integration. The collaboration with NGK extends the application of ceramic substrates to higher power and thermal scenarios.

NGK aims to integrate PanelSemi's circuit fabrication technology with its own products, including the ultra-compact EnerCera lithium-ion rechargeable battery, ceramic substrates, and ceramic packages. PanelSemi's HyBrid Substrate (HBS) technology platform features ultra-fine line width and spacing achieved through Thin Film (TF) and Panel Level Packaging (PLP) processes. HBS enables high-density interconnection, functioning as both an interposer and package substrate in advanced packaging, with the top die directly bonded to the HBS.

Dr. Larry Zu, Founder and CEO of Sarcina Technology, the Application Specific Advanced Packaging (ASAP) Design Service and Production leader, predicted that recent Bump Pitch Transformer (BPT) designs will speed 2.5D IC advanced packaging adoption to meet the red-hot demand for AI innovation. In remarks made in the Keysight Theater at the 61st Design Automation Conference, he envisioned new BPT technology paving the way for new artificial intelligence computing opportunities.

"We believe that the Bump Pitch Transformer architecture will accelerate the growth rate of 2.5D semiconductor packages that are key to meeting the explosive demand for AI-driven computing capabilities," Dr. Zu said during his address in the Keysight Theater.

TSMC is working on a new advanced chip packaging technology that uses rectangular panel-like substrates instead of the traditional circular wafers, according to a Nikkei report citing sources. This new approach would allow more chips to be placed on a single substrate. TSMC is reportedly experimenting with rectangular substrates measuring 515 mm by 510 mm, providing more than three times the usable area compared to current 12-inch wafers. Using a rectangular-shaped wafer can potentially eliminate more of the incomplete chips found on the edges of current circular ones. While this may sound simple, it would actually require a radical change to the entire manufacturing process.

While the research is still in its early stages and may take several years to reach mass production, it represents a major technological shift for TSMC. The company has responded to Nikkei's inquiry by stating that they are closely monitoring advancements in advanced packaging technologies, including panel-level packaging. This development could potentially give TSMC an edge in meeting future chip demands, however, Intel and Samsung are also testing this new approach.

The Samsung Group has formed a new cross-department alliance—according to South Korea's Sedaily—this joint operation will concentrate on the research and development of a "dream substrate." The company's Electronics, Electrical Engineering, and Display divisions are collaborating in order to accelerate commercialization of "glass substrate" chip packaging. Last September, Intel revealed its intention to become an industry leader in "glass substrate production for next-generation advanced packaging." Team Blue's shiny new Arizona fabrication site will be taking on this challenge, following ten years of internal R&D work. Industry watchdogs reckon that mass production—in North America—is not expected to kick off anytime soon. Sensible guesstimates suggest a start date somewhere in 2030.

The Sedaily article states that Samsung's triple department alliance will target "commercialization faster than Intel." Company representatives—in attendance at CES 2024—set a 2026 window as their commencement goal for advanced glass substrate chip package mass production. An unnamed South Korean industry watcher has welcomed a new entrant on the field: "as each company possesses the world's best technology, synergies will be maximized in glass substrate research, which is a promising field...it is also important to watch how the glass substrate ecosystem of Samsung's joint venture will be established." Glass substrate packaging is ideal for "large-area and high-performance chip combinations" due to inherent heat-resistant properties and material strength. So far, the semiconductor industry has struggled with its development—hence the continued reliance on plastic boards and organic materials.

What's New: Intel today announced one of the industry's first glass substrates for next-generation advanced packaging, planned for the latter part of this decade. This breakthrough achievement will enable the continued scaling of transistors in a package and advance Moore's Law to deliver data-centric applications.

"After a decade of research, Intel has achieved industry-leading glass substrates for advanced packaging. We look forward to delivering these cutting-edge technologies that will benefit our key players and foundry customers for decades to come."
-Babak Sabi, Intel senior vice president and general manager of Assembly and Test Development

Samsung Electronics, a world leader in advanced semiconductor technology, today announced its latest foundry technology innovations and business strategy at the 7th annual Samsung Foundry Forum (SFF) 2023. Under the theme "Innovation Beyond Boundaries," this year's forum delved into Samsung Foundry's mission to address customer needs in the artificial intelligence (AI) era through advanced semiconductor technology.

Over 700 guests, from customers and partners of Samsung Foundry, attended this year's event, of which 38 companies hosted their own booths to share the latest technology trends in the foundry industry.

The bipartisan Protecting Circuit Boards and Substrates Act of 2023 introduced by Representatives Blake Moore (R-UT-1) and Anna Eshoo (D-CA-16) finishes the job the CHIPS Act began by incentivizing investment in the domestic printed circuit board (PCB) industry. This bill is a necessary follow-on to the CHIPS Act: without a trusted, reliable domestic source of PCBs and substrates, computer chips don't connect to end use electronic devices.

Domestic PCB production shrunk over the past 20 years, falling from 30% to barely 4% of the world's supply. Ninety percent of the world's supply now comes from Asia…56% in China alone.

Dai Nippon Printing Co., Ltd. (DNP) has developed a Glass Core Substrate (GCS) targeting next-generation semiconductor packages. The new product replaces conventional resin substrates (ex. FC-BGA: Flip Chip-Ball Grid Array) with a glass substrate. Through the use of high-density Through Glass Via (TGV), it is now possible to provide a higher performance semiconductor package than that based on currently available technology. In addition, by adapting our panel manufacturing process, the new product can also support demands for high efficiency and large-scale substrate.

Features
Fine pitch and high reliability
The newly developed GCS includes a TGV necessary for electrically connecting the fine metal wiring configured on the front and back of the glass. It is a Conformal Type glass substrate in which a metal layer is adhered to the side walls of the via. Our new proprietary manufacturing method enhances the adhesion between glass and metal, which was difficult to achieve with conventional technology, to realize fine pitch and high reliability.
