Key Applications

  • Semiconductor Interconnects

ALD/CVD precursor for cobalt films in advanced nodes, replacing copper in interconnect metallization.

  • Low-Resistivity Cobalt Layers

Provides uniform, conformal films with excellent electrical performance for logic and memory chips.

  • Advanced Packaging 

Applied in barrier/liner and seed layer deposition for 3D integration and high-aspect-ratio structures.

  • Catalysis

Precursor for selective organometallic transformations such as Nicholas and Pauson–Khand reactions.

  • Materials Research

Used in the synthesis of novel cobalt complexes and nanostructured materials.


Custom packaging for R&D or production scale.
