Why Use A Low Pressure Chemical Vapor Deposition LPCVD furnace system

classify :Product knowledge

Low Pressure Chemical Vapor Deposition LPCVD furnace system is the process of molecules moving from an area of high concentration to a low one. It occurs routinely within and between liquids, gases, and solids in daily life. This process is exploited by diffusion furnace, which elevate the temperature of work pieces and introduce gaseous elements to encourage solid state diffusion. Solid state diffusion occurs when molecules of a substance mix with a host solid at the atomic level. This mechanism of diffusion was a scientific curiosity for many years but has since become an integral process in semiconductor manufacturing.

 

We engineered a water-cooled diffusion furnace that can reach 1350°C in 10 minutes, as well as cool down below 800°C in a mere 2 minutes. Controlled graphene growth is ensured, and processing times are kept to a minimum with the Low Pressure Chemical Vapor Deposition LPCVD system. Various chamber tube sizes are available between Ø 2 in -- Ø 12 in allowing processing of single small samples up to batches in 6-inch wafers
