Hot Filament Chemical Vapor Deposition

With widespread use of electronic devices the semiconductor industry has seen a lot of changes in manufacture of semiconductor devices.

Out of various stages for semiconductor manufacturing, fabrication process is one of the most important steps. For fabrication of functional layers over a substrate, the most commonly used technique is CVD (Chemical vapor Deposition).

CVD is done in various processes. One of them is HFCVD (Hot Filament Chemical Vapor Deposition). The Blue Wave hot filament chemical vapor deposition system was built to produce concentrated, dense, adherent and coherent poly-crystalline diamond films on silicon, metallic and ceramic substrates.

The HFCVD mechanism is advantageous as it provides the poly-crystalline deposits of considerable uniform micro-structure. It can be scaled for production or large area deposition at lower cost.

The machine is designed to deposit various forms of diamond coatings (UNCD-ultra nano crystalline diamond, NCD-nano crystalline diamond) poly-crystalline diamond films and 2D carbon- that is graphene, which have broad use in electronic industry.
