Intel Patent Reveals Micro LED Chips Embedded in Glass Processors
Intel filed a patent detailing a method to embed Micro LED chips partially or entirely inside the glass substrates of semiconductor processors, diit.cz reported. The design features through-glass vias (TGVs) to supply power directly to the LEDs, which can utilize nanodire-structured red, green, and blue pixels. While the patent points to potential status signaling and aesthetic lighting features, current processor designs utilize massive cooling solutions that would obstruct visibility.
Lasers and chemical etching create conductive channels
The manufacturing process outlined in the patent relies on lasers and chemical etching to carve out cavities for the semiconductor chips and create the through-glass vias. Manufacturers would then apply copper galvanically to complete the electrical connections. The micro-scale LEDs can sit either horizontally or vertically within the substrate, while integrated micro-mirrors and reflectors direct the light outward through the glass window.
Timeline of Intel Glass Substrate Development
- 2022: Intel files the patent describing Micro LED integration within glass processor packaging.
- 2023: The company makes its first public disclosures regarding the broader development of glass substrates.
- 2024: Leadership under then-CEO Pat Gelsinger releases extensive deployment plans targeting conventional CPUs, GPUs, and AI accelerators.
- Current CEO Lip-Bu Tan scales back the original capital expenditure and investment roadmap.
- Deployment is delayed until at least 2029, shifting initial deployment to alternative product categories.
How Micro LEDs receive power and display colors
How do the Micro LEDs receive power inside the glass substrate?
Power reaches the embedded Micro LEDs through through-glass vias (TGVs), which are microscopic conductive channels laser-drilled and chemically etched directly into the glass packaging.
What colors can the embedded Micro LEDs display?
The patent specifies that the Micro LEDs can use a nanowire structure to emit red, green, and blue light.
Are these illuminated glass substrates available in current Intel processors?
No, the commercial release of Intel glass substrates has been delayed to at least 2029, and planned implementations for high-performance CPUs and AI accelerators have been revised under current leadership.
