LPCVD

Designed and manufactured to meet the high temperature and rapid cooling requirements of graphene and CNT research, Angstrom’s LPCVD (Low Pressure Chemical Vapor Deposition) system will fit in nicely in your lab.

Low pressure chemical vapor deposition LPCVD system

We engineered a water cooled furnace that can reach 1100°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.  Various chamber tube sizes are available between Ø2in and Ø8in allowing processing of single small samples up to batches in 6 inch wafers.

  • Simple to use yet highly advanced integrated software platform
  • PC/PLC controlled recipes for single, batch, or automated processes
  • Advanced data logging and process tracking ensure consistent and repeatable processes
  • High resolution control provides impressive low rate stability and consistent doping ratios
  • Central control station manages each module and schedules the processes in each chamber
  • Independent control of multiple chambers (when applicable in cluster or connected configurations)
  • Complex recipes can be created and modified easily
  • Automatic PID control loop tuning significantly reduces process development time

From the time it was delivered, this laboratory system has performed nearly flawlessly, arguably extending our capabilities well beyond those currently attainable by any organic thin film laboratory in the world. I attribute the success of this entire system to the excellence of the engineering as well as the cooperative nature of the Angstrom team in taking our best designs and making them better during the system construction process.
