Abstract

PURPOSE: To improve the frequency characteristics of an electron emission amplifier tube by providing an insulator layer to surround a diode active area in a semiconductor substrate layer.
CONSTITUTION: A diode is formed by providing a semiconductor layer 3 in the vicinity of the surface of a semiconductor layer 2 formed on a semiconductor substrate 1. A porous insulator layer 21 is provided in the layer 2 to surround the periphery of the diode active area, and a porous insulator layer 22 is further provided from the layer 21 on the layer 2 to coat the periphery of the diode active area. A thin metallic layer 5 for passing primary electron is provided on the active area, and a thick metallic layer 6 is provided further on the periphery of the layer 5 to coat only the layer 21 on the layer 22. Since the layer 6 is thus coated on the layer 22 to thereby reduce the static capacity of capacitors C4-C6 as compared with the conventional one to thus reduce the static capacity of the target, it can improve the frequency characteristics of the amplifier.
