Abstract:
A vacuum integrated electronic device (120) has an anode region (101) of conductive material; an insulating region (102, 104) on top of the anode region; a cavity (54) extending through the insulating region and having a sidewall (53); and a cathode region (109). The cathode region has a tip portion (51, 52) extending peripherally within the cavity, adjacent to the sidewall of the cavity. The cathode region is formed by tilted deposition, carried out at an angle of 30-60° with respect to a perpendicular to the surface of device.
