Patent ID: 8643258

Claim:
An electron multiplying apparatus, comprising: a glass base composed of glass material; and an electron multiplying section fixed on a top surface of the glass base and composed of silicon, the electron multiplying section comprising a plurality of electrodes and bottom portions each positioned between the adjacent electrodes, each of the electrodes being processed in a shape such that each of the electrodes stands with respect to the top surface of the glass base by etching a silicon substrate from an upper surface thereof opposing a bottom surface thereof joined toward the top surface of the glass base, wherein both of the electrodes and bottom portions cover the top surface of the glass base while being in direct contact with the top surface of the glass base, and wherein each of the electrodes has a side surface of which at least part is provided with a secondary electron emission surface, whereby electrons are cascade-multiplied along the top surface of the glass base by the secondary electron emission surfaces of the electrodes.
