Abstract

A charged particle counting device, a manufacturing method thereof, and a charged particle counting system are provided. The charged particle counting device includes: a bipolar transistor () and a magneto-electric induction coil (), a gate () of the bipolar transistor is electrically connected to an end of the magneto-electric induction coil, and the other end of the magneto-electric induction coil is applied with a constant voltage, when a stream of positively charged particles passes through the magneto-electric induction coil and a first induced voltage generated by the magneto-electric induction coil is greater than a predetermined voltage threshold, a channel of the bipolar transistor is an N-type channel; and when a stream of negatively charged particles passes through the magneto-electric induction coil and a second induced voltage generated by the magneto-electric induction coil is less than the predetermined voltage threshold, the channel of the bipolar transistor is a P-type channel.
