The light collection region collects photo-generated charge carriers and is disposed within the second epitaxial layer.
光收集区域收集光生电荷载流子并被布置在第二外延层内。
By utilizing the method, the doping concentration of the epitaxial layer is regulated to increase the widening of the depletion region so as to further improve the photon absorption efficiency.
利用本发明的方法，通过外延层的掺杂浓度来调节以增加耗尽区的展宽，可进一步提高光子吸收效率。
