Eindhoven, Friday 6 November 2026
With capital spending nearing $28 billion this year, advanced packaging revenue will surpass traditional methods for the first time as artificial intelligence infrastructure demands outpace physical transistor scaling.

Capital Realignment and the Shift Beyond Monolithic Silicon

The global semiconductor landscape is experiencing an architectural transition as artificial intelligence workloads outstrip traditional front-end transistor scaling [1][5]. For decades, back-end packaging was regarded as a secondary assembly phase, yet escalating costs and thermal boundaries have thrust multi-die integration into the core of semiconductor economics [1][5][6]. Pat Gelsinger, partner at Playground Global and former chief executive of Intel, previously observed that ‘packaging was always that thing that you just didn’t worry about’ [1]. That paradigm has shifted entirely: in 2026, research firm Yole Group projects capital spending dedicated to advanced packaging will approach $28 billion, enabling advanced packaging market revenue to eclipse traditional assembly methods for the first time in history [1]. Instead of relying exclusively on single-die System-on-Chip (SoC) architectures, high-performance computing now mandates modular chiplet platforms combining distinct compute dies, accelerators, and stacked high-bandwidth memory [1][4][5].

The Capacity Crunch: Financing Back-End Diversity

Capacity bottlenecks across high-performance packaging lines continue to constrain leading AI platform deliveries [1]. As of Friday, 6 November 2026, Nvidia is actively injecting billions of dollars into Taiwan-based Siliconware Precision Industries (SPIL), an operating unit of ASE Technology, to accelerate the manufacturing expansion of chip-on-wafer-on-substrate (CoWoS) packaging lines [1]. While Taiwan Semiconductor Manufacturing Company (TSMC) maintains market hegemony over CoWoS technologies leveraged by hyperscalers, Nvidia, AMD, and Broadcom, the acute shortfall in throughput has triggered an industry-wide push towards alternatives [1]. Powertech Technology Chairman D. K. Tsai captured the sentiment by stating that ‘everyone is looking for a solution outside TSMC’, with Senior Vice President Jim Lin affirming that ‘the most important thing right now is capacity’ [1]. In response, AMD has committed investments exceeding US$ 10 billion across the Taiwanese semiconductor ecosystem, forging multi-faceted packaging arrangements with ASE, SPIL, and Powertech [1]. Chief Executive Lisa Su underlined that ‘CoWoS and advanced packaging are super important for our high-performance computing going forward’ [1].

Architectural Diversification: Panels, Hybrid Bonding, and Thermal Frontiers

To circumvent physical surface-area limits and reduce substrate scrap, chip designers and outsourced semiconductor assembly and test (OSAT) suppliers are transitioning from round silicon wafers to massive rectangular substrates [1]. Powertech is developing panel-level packaging alongside AMD and Broadcom to process larger AI die clusters, while formalising plans to invest US$ 400 million in an advanced packaging joint venture with Broadcom in Singapore [1]. Concurrently, TSMC built a pilot production line for its proprietary chip-on-panel-on-substrate (CoPoS) technology in April 2026 [1]. Beyond packaging form factors, extreme power density requires cutting-edge material engineering; on 3 November 2026, Element Six and Entegris unveiled a strategic alliance to integrate synthetic diamond—noted for holding the highest room-temperature thermal conductivity of any known material—into advanced packaging designs for next-generation graphics processing units and radio frequency silicon [6]. As Entegris Chief Innovation Officer Olivier Blachier stated, the primary objective is engineering resilient surfaces and novel bonding approaches that withstand high power densities [6].

The Benelux Corridor and Europe’s Strategic Packaging Framework

Against this global backdrop, Europe’s semiconductor nerve centre—anchored by the research and industrial cluster across Leuven, Eindhoven, and the broader Benelux region—is positioning advanced packaging and heterogeneous integration as critical pillars of supply chain sovereignty [2][3][4]. At the upcoming SEMICON Europa 2026 gathering scheduled between 10 November and 13 November at Messe München, industry leaders will evaluate how European fabs and packaging strategies converge [3]. SEMI Europe President Laith Altimime stressed that advanced packaging constitutes a strategic pillar of continental resilience by unifying compound semiconductors, chiplets, and integrated photonics [3]. Imec Chief Executive Patrick Vandenameele similarly pointed out that semiconductor progress now demands innovation at the crossroads of chiplets, silicon photonics, and memory integration [3]. In complementary edge domains, Dr. Peter Vandersteegen, Portfolio Manager Automotive at imec, emphasised at ISIG India 2026 that open chiplet architectures and advanced packaging provide the scalable foundation needed to transition high-performance Physical AI from data centres to autonomous vehicles and smart robotics without violating stringent power budgets [4].

Supply Chain Resilience and Smart Automation Integration

The push to anchor advanced packaging and high-tech manufacturing within Europe directly confronts systemic supply chain vulnerabilities [2][3][5]. In the Netherlands, where regional manufacturing firms and high-precision suppliers interface with foundational equipment developers such as ASML and ASM [GPT], local ecosystems are pursuing radical automation to offset geopolitical dependencies and international cost disadvantages [2]. Reports published on 6 November 2026 by Link Magazine highlight that Dutch manufacturing competitiveness against Asian rivals relies fundamentally on tightly integrated supply chains, automated assembly, and front-end collaborative engineering rather than cut-throat unit pricing [2]. As TNO warned earlier in 2026, high-wage European manufacturing requires systemic robotisation and front-end ‘design for assembly’ practices to retain high-tech relevance [2]. By blending automated regional manufacturing clusters with imec’s heterogenous packaging innovations and deep-tech materials development, the European semiconductor ecosystem is creating an interconnected front that bridges the gap between pure chip design, high-density packaging, and sovereign infrastructure deployment [2][3][4][5].
