ChEmpower's Chakra™ Pad Aims to Revolutionize Chip Manufacturing

PORTLAND, Ore. – February 11, 2026 – In a move poised to redefine a critical step in semiconductor manufacturing, Portland-based ChEmpower has introduced Chakra™, a technology it calls the industry’s first functional polishing pad for abrasive-free planarization. The innovation targets the persistent challenges of defects and precision in chipmaking, aiming to replace a decades-old process with a chemically driven solution designed for the demanding requirements of AI processors, High-Bandwidth Memory (HBM), and advanced 3D packaging.

For decades, the semiconductor industry has relied on Chemical Mechanical Planarization (CMP) to achieve the atomically smooth, flat surfaces necessary to build complex integrated circuits. This process traditionally involves pressing a rotating wafer against a polishing pad while a slurry containing abrasive particles mechanically scrubs the surface. While effective, this method is a primary source of costly defects, including microscopic scratches and particle contamination, which can render a multi-million-dollar chip useless. As chip features shrink to the single-digit nanometer scale, this long-standing issue has become a critical bottleneck, with some fabs attributing 5% to 10% of yield loss directly to CMP-related defects.

ChEmpower’s Chakra™ technology proposes a radical departure from this paradigm. Instead of a passive pad assisting a mechanical grinding process, Chakra™ is an active component in a precisely controlled chemical reaction.

A Fundamental Shift from Abrasion to Chemistry

The core of the new technology is what the company describes as a three-element reactive system: the Chakra™ functional pad, a proprietary chemical polishing fluid, and the target material on the wafer. Unlike conventional pads that serve as a carrier for abrasive slurries, the Chakra™ pad is engineered with functional chemical groups on its surface. Material removal occurs only at the precise points where the pad, the specialized fluid, and the wafer’s high points interact, initiating a controlled chemical reaction that dissolves material away rather than scraping it.

“Chakra™ is more than a pad; it’s a functional material that actively drives the CMP process,” said Sudhanshu Misra, CEO and co-founder of ChEmpower, in the company's announcement. “Its name, meaning ‘wheel of power’, reflects its role as the central, enabling force in our planarization system. Paired with our chemical polishing fluid, it delivers truly abrasive-free planarization, improving yield, reducing cost, and supporting next-generation AI chips and packaging.”

By eliminating abrasive particles entirely, the system is designed to sidestep the root cause of scratches and contamination that plague conventional CMP. This chemical-centric approach also provides greater selectivity, allowing the process to remove a target material like copper with high precision while stopping on underlying barrier or dielectric layers. This level of control is paramount for fabricating the dense, multi-layered interconnects found in modern high-performance chips.

Unlocking Performance for AI and Advanced Packaging

The timing of ChEmpower's innovation aligns directly with the explosive growth of AI and the industry's shift toward advanced packaging techniques like hybrid bonding. These next-generation technologies place unprecedented demands on surface quality. Hybrid bonding, which enables direct copper-to-copper connections between stacked chips or chiplets, requires surfaces to be virtually perfect. Any particle residue, dishing, or surface irregularity can compromise the bond's integrity, leading to device failure.

The vertical stacking used in HBM, which is essential for the massive memory bandwidth required by AI accelerators, similarly depends on flawless planarization of through-silicon vias (TSVs) and interconnects. Traditional abrasive CMP struggles to deliver the necessary uniformity and defect-free surfaces consistently across these complex 3D structures.

“Advanced interconnects and hybrid bonding require exceptional surface integrity and precision,” noted Professor Babu, the company's CTO and co-founder. “Chakra™ was designed from the ground up as a functional material rather than a consumable. By eliminating abrasives and enabling controlled chemical reactions, Chakra™ delivers the surface quality and consistency needed for next-generation AI chips and advanced packaging.”

By providing a path to smoother, cleaner surfaces, the technology promises to improve the yield and reliability of these high-value components, potentially accelerating the performance roadmap for the entire high-performance computing sector.

The Economic and Sustainable Imperative

Beyond the technical benefits, ChEmpower is positioning its abrasive-free platform as a solution to significant economic and environmental pain points in semiconductor fabrication. The abrasive nature of traditional CMP leads to considerable wear and tear on multi-million-dollar polishing equipment, necessitating frequent maintenance and replacement of components, which reduces tool uptime and adds operational cost.

By removing the abrasive element, the Chakra™ system is expected to significantly extend pad life and reduce equipment wear, contributing to a lower overall cost of ownership for manufacturers. Furthermore, the company reports that its technology is currently being evaluated through pilot programs at multiple semiconductor fabs, with early results demonstrating compatibility with existing CMP platforms. This drop-in capability is crucial, as it lowers the barrier to adoption by allowing fabs to integrate the new technology without a complete overhaul of their production lines.

Equally compelling are the sustainability claims. The semiconductor industry is a notoriously heavy user of water and producer of chemical waste. Planarization alone can account for up to 40% of a fabrication plant's total water consumption. ChEmpower asserts that its benign, particle-free chemical formulations not only eliminate abrasive slurry waste but also support advanced water and metal reclamation. Patented aspects of the technology allow for the removed metal—such as copper—to be captured from the effluent, aligning with circular economy principles and reducing the environmental footprint of chip manufacturing.

Market Adoption and Future Trajectory

ChEmpower is entering a market long dominated by established materials giants like DuPont, Entegris, and Fujimi. However, by targeting the industry's most acute pain points with a fundamentally different approach, the company is positioning itself as a key enabler for the next wave of semiconductor innovation. The ongoing pilot programs, which reportedly involve leading logic and memory chipmakers, will be the ultimate test of the technology's readiness for high-volume manufacturing.

The company's initial offering, the Chakra™ Copper Series, is focused on the copper interconnects that form the wiring of modern chips. However, the roadmap includes expanding the functional pad technology to a wide range of other materials, including refractory metals, silicon, and various oxides. This planned expansion signals a broader ambition to provide a comprehensive, abrasive-free planarization platform for a multitude of applications across the semiconductor manufacturing flow. Chakra™ functional pads and their corresponding chemical polishing fluids are now available to qualified customers, marking a critical step in the transition from development to commercial-scale deployment.
