IPC: G01R33/06
Filed: 1989-06-08
Abstract: PURPOSE:To enhance a detection sensitivity of a magnetic field by a method wherein a collector is installed additionally between two collectors and carriers which are not required to detect the magnetic field are removed by this collector. CONSTITUTION:Bases B1 to B4 (14 to 17) are formed on a substrate 12; in addition, collectors C1 to C3 (19 to 21) are formed at nearly equal intervals at a nearly equal distance from an emitter E (18) and an emitter electrode E 18. Consequently, carriers from the emitter 18 are accelerated in a direction of the collectors 19 to 21 by means of the bases B1 to B4; the carriers which are required to detect a magnetic field reach the collectors 19 and 21 as collector output electrodes and are detected. As a result; the carriers which advance straight to the collector 20 from the emitter 18 are not required to detect the magnetic field and are taken out by the collector C3 (20) so that a detection of the magnetic field by the collectors C1, C2 is not affected. Thereby, it is possible to increase a detection accuracy of the magnetic field.
