In this paper the development and fabrication of the pressure sensor based on electron field emission from carbon nanotubes (CNTs) was described. The sensor consisted of two parts: a silicon membrane as an anode; and multi-walled CNTs on a silicon cathode, creating a vacuum micro-chamber. Both electrodes were fabricated from the silicon single crystal (Si) wafer of an orientation <100> doped by phosphorus. The CNTs were grown by a plasma enhanced CVD using an iron catalyst in an atmospheric pressure microwave torch. The catalyst was patterned into an area corresponding to the membrane dimensions. The thin CNTs with a diameter of about 80 nm were standing vertically perpendicular to the substrate due to a crowding effect. In order to find the threshold current, the emission characteristics of prepared sensors were measured.
