Semiconductor progress has long been defined by the pursuit of smaller, faster, and more efficient designs. Moore’s Law, the observation that transistor density doubles roughly every two years, shaped how the industry measured success. But that pattern no longer captures the full story. Erik Hosler, a strategist with deep experience in lithography and system-level design, is part of the shift toward broader ways of thinking about technological advancement.
Many in the industry now view Moore’s Law less as a physical rule and more as a mindset. Even as transistor miniaturization slows, the drive to improve performance, efficiency, and functionality remains constant. Thinking beyond density allows the industry to explore new architectures, integrate emerging technologies, and redefine what progress looks like.
The Narrow View of Moore’s Law Is Holding Us Back
For many years, Moore’s Law was closely associated with a single idea. Transistor density became the primary measure of progress, and engineers focused on fitting more features into smaller spaces. That effort led to major gains in computing power, energy efficiency, and cost per operation.
As scaling reached the single-digit nanometer range, new challenges began to appear. Quantum tunneling, power leakage, and rising fabrication costs made continued miniaturization more difficult. At the same time, computing demands were shifting. Devices needed to do more than run faster. They had to respond in real time, support new forms of connectivity, and adapt to a wider range of use cases. In this environment, Moore’s Law can no longer be defined by lithography alone.
A Broader Interpretation of Progress
What if Moore’s Law was never about size? What if its true spirit was consistent, measurable improvement in the capabilities of electronic systems? That broader framing opens new directions for innovation.
Today’s systems benefit from architectural advances, software optimization, system-on-chip integration, and domain-specific acceleration. Progress might come from a better memory hierarchy, a more efficient AI core, or a tighter coupling between sensing and processing. Each of these pushes computing forward, even if transistor counts remain flat. Seen this way, Moore’s Law is not dead; it is diversifying.
Embracing Cross-Sector Innovation
A key element of this mindset shift is recognizing the role of collaboration across traditionally separate fields. Mechanical engineering, materials science, photonics, systems design, and artificial intelligence are no longer distant disciplines. Their convergence defines the next phase of semiconductor development.
This theme resonated strongly at the SPIE Advanced Lithography symposium, where industry experts acknowledged the collective effort required to sustain innovation. Erik Hosler says, “It’s going to involve innovation across multiple different sectors.”
It reflects a shift in how the industry approaches progress. The future of Moore’s Law, as a guiding principle, will depend on how effectively different sectors work together to address increasingly complex challenges.
Systems Thinking Over Component Optimization
Traditional chip development focuses on individual component optimization. Each domain has its trajectory: faster transistors, better interconnects, and more efficient power delivery.
Now, the emphasis is shifting toward holistic systems of thinking. Performance gains increasingly come from how well components work together. Packaging, data flow, thermal management, and real-time adaptability all play a role.
System-level optimization leads to unexpected gains. For example, better coordination between software and hardware can reduce unnecessary processing, saving both power and latency. Integration of sensors directly into computer platforms enables faster and more accurate decision-making. This shift aligns well with Moore’s Law’s mindset as a framework for creative problem-solving, not just technical scaling.
Photonics and MEMS: Functional Scaling in Action
When viewed as a mindset, Moore’s Law encourages the industry to explore alternatives to density-based performance. Photonics and MEMS are perfect examples.
Photonics offers low-power, high-bandwidth data transmission that bypasses the limits of electrical interconnects. MEMS adds sensing and actuation capabilities that allow systems to interact with the physical world.
These technologies don’t just extend Moore’s Law; they reinvent it. They demonstrate that scaling can mean adding functions, improving efficiency, and opening new applications. By focusing on function rather than feature size, the industry gains a much wider canvas for progress.
Education Must Support the Mindset Shift
Reframing Moore’s Law also means rethinking how future engineers are trained. A narrow focus on transistor design or process nodes no longer prepares students for the challenges ahead. They must be educated in systems thinking, integration, and collaborative design.
Courses that blend electronics, optics, materials, and software are gaining popularity. Interdisciplinary labs and industry partnerships are helping students connect theory to practice. The workforce that will drive the next 50 years of semiconductor innovation must be equipped to operate beyond silos. They need the mindset Moore’s Law now demands, one that seeks progress everywhere, not just along a single axis.
Metrics That Reflect the New Era
If transistor density no longer tells the whole story, what should take its place? The answer lies in application-driven metrics. System-level benchmarks like energy efficiency, total cost of ownership, latency, and adaptability are now more relevant.
A processor that responds to environmental inputs, adapts workloads in real-time and uses less power underload might outperform a denser chip that lacks those capabilities. By adopting new metrics, the industry can more accurately reflect the type of progress that matters to users, developers, and businesses alike.
Moore’s mindset remains focused on delivering more for less, but “more” and “less” must be defined in ways that match today’s challenges.
The Role of Policy and Business Models
Reframing Moore’s Law also has implications beyond fabrication. Business models, funding strategies, and public-private partnerships must reflect the interdisciplinary nature of modern innovation.
Government programs that support AI, quantum computing, advanced packaging, and workforce development all contribute to the new ecosystem. Startups working in niche domains, whether novel materials, chiplet design, or edge photonics, are critical to the overall progress. A broader mindset means recognizing the contribution of smaller players and enabling policies that support ecosystem-wide collaboration.
A Culture of Continuous Reinvention
The most enduring feature of Moore’s Law is the culture it created: one continuous reinvention. Every time a limit was reached, novel solutions emerged. That attitude remains critical today.
Whether through multi-die integration, energy-aware computing, or light-based signaling, the industry continues to push forward, not by repeating the past but by redefining success. Moore’s Law is best honored not by preserving its original form but by applying its intent to the problems of the present.
Scaling Mindset, Not Just Technology
Moore’s Law began as a curve on a chart. Over time, it became a goal, a measuring stick, and a promise. Today, it must become a mindset that values system-level innovation, cross-sector collaboration, and user-focused performance. One that invites innovative technologies into the fold and redefines progress in broader terms.
By treating Moore’s Law not as a law of physics but as a principle of continuous improvement, the semiconductor industry can continue to thrive. It may no longer be about doubling transistors, but it remains very much about doubling possibilities.
