Diamond Heat Spreader

 

The Diamond Heat Spreader is a highly efficient thermal management material engineered for the most demanding high-power electronic devices. Featuring extremely high thermal conductivity and exceptional thermal stability, it rapidly transfers heat away from the heat source, significantly reducing the device’s operating temperature while improving overall system stability and lifespan.

With a thermal conductivity reaching up to 2000 W/m·K—which is 5 times that of copper and 10 times that of aluminum—diamond heat spreaders offer unparalleled heat dissipation performance.

IDM Customization Service

From advanced processes to specialty processes, we use our IDM vertical integration experience to help customers overcome design-process collaboration challenges.

01

Supports advanced nodes such as [5-22nm FinFET/BCD/GAA] to meet the needs of high-performance computing (HPC), AI chips, etc.

02

MPW (Multi-Project Wafer) Service: Small batch trial production to reduce customers' initial costs. Customized process development: Cooperate with customers to conduct DTCO (Design-Process Co-Optimization), customize design rules and process parameters.

03

We support the joint solution of "wafer foundry + advanced packaging" (such as 3D IC, heterogeneous integration) to avoid the loss of multi-supplier collaboration. Unlike pure foundries, we verify the process stability through mass production of our own chips to reduce the risk of tape-out for you.
