Harness the key building block for next generation in semiconductors

Discover our « Bleu » series of homogeneously monocrystalline boron-doped diamond (BDD) plates synthesized by chemical vapor deposition (CVD).

Our « Bleu » diamonds contain significant amounts of boron impurities (up to 0.1%), which allows their electrical conductivity to be controlled, paving the way for their use as basic building block for vertical components in power electronics.

Our pledge

High Quality

Exceptional impurity and defect levels

Custom design
