Advanced Diamond Materials for Heat Management

M10 and M11 single-crystal diamonds deliver industry-leading thermal conductivity and precision engineering for high-performance chips and lasers.

How Northern Carbon Improves Heat Management

Northern Carbon’s single-crystal diamond plates are engineered to remove concentrated heat from the most demanding electronic devices. By spreading heat rapidly in both lateral and vertical directions, M10 and M11 help reduce hotspots, improve reliability, and support higher sustained performance.

Why it Matters

Heat Limits Performance

Chips generate 45-65% of their power as heat; hotspots reduce performance and efficiency.

Diamond Spreads Heat Faster

M10 and M11 plates transfer heat 5× faster than copper, spreading heat laterally to prevent hotspots.

Cooler Chips Last Longer

Reducing junction temperature by 10°C can double a chip’s lifespan.

Technical Overview

M10 and M11 are engineered for advanced semiconductor and photonic applications where traditional materials fall short. Each product combines high thermal conductivity, tight geometric tolerances, and precision surface finishing to support reliable system integration.
