Abstract

PURPOSE:To facilitate the manufacture improving the manufcturing efficiency by a method wherein the heattreatment after forming the element for the photoelectric conversion element comprising the photoreading device converting the light sugnals of the image data into the electric signals is performed by means of the laser beam radiation. CONSTITUTION:Multiple photoelectric conversion elements 13 fixed to the tape carrier 14 along the reading line 12 on the substrate 11 having the input and output terminals 15 are arranged forming into the photoreading device 10. In this constitution, said elements 13 are formed according to the procedures as mentioned below, i.e. the first transparent electrode layer 2 comprising In2O3, the N type semiconductor layer 3 using CdS, the P type semiconductor layer 4 using CdTe and the second transparent electrode layer 5 using Au or Te are laminated on the glass substrate 1 forming into the diode. Then the P-N junction between said layers 3 and 4 is heated by means of the radiation of the laser beam 7 of the laser 6 traveling from the back side of said substrate 1 as well as the injection of the energy from the side with the most intensive band energy to the side with the least intensive band energy.
