Description of Rectangular 4N C Carbon Target

Our Rectangular 4N C Carbon Target fixes common issues for carbon‑based thin‑film deposition. Standard rectangular carbon targets often suffer from loose microstructure and particle flaking, creating contamination and uneven films that ruin your test samples. We adopt high‑purity carbon raw material and optimized pressing and sintering processes to build a dense, homogeneous target body. This tight microstructure reduces particulate shedding during sputtering, delivering consistent carbon films ideal for tribological coatings, semiconductor masking, and carbon material R&D. Every target is inspected for purity and surface quality before shipment. Backing plate bonding is available to keep performance stable inside your sputtering chamber. We can adjust dimensions to match your rectangular fixture. Cut down wasted substrates caused by particle defects, so you can focus your lab work on getting reliable surface and tribology measurement data for your coating development.
