Title: Photodiode
Inventor: FUJIEDA ICHIRO
IPC: H01L31/10
Filed: 1993-07-26
Abstract: PURPOSE:To turn a photovoltaic photodiode depleted at a low voltage by a method wherein a region which holds a fixed spatial charge in parallel with a negative electrode and a positive electrode is formed on a semiconductor film located between the negative electrode and the positive electrode. CONSTITUTION:An a-Si layer 10 is deposited on an insulating substrate to form a photoelectric conversion semiconductor film. Then, boron is selectively introduced to form a P-type a-Si layer 11 which serves as an electrode to prevent electrons from being injected into the a-Si layer 10, and phosphorus is selectively introduced to form an N-type a-Si layer 12 which serves as an electrode to prevent holes from being injected into the a-Si layer 10. Then, a P-type a-Si layer 13 of low concentration is formed into a belt in parallel with the P-type a-Si layer 11 and the N-type a-Si layer 12. A negative fixed spatial charge is present in the P-type a-Si layer 13 to lessen a low electrical field region around the N-type a-Si layer 12. By this setup, a photovoltaic type photodiode of this constitution can be turned depleted on a low voltage and simplified in structure.
