The utility model belongs to the technical field of processing of semiconductor devices, and particularly relates to a semi-spherical optical path structure of a photoelectric coupler, which is characterized in that transparent colloid is sealed and cast on the surfaces of all photosensitive chips and infrared chips in a photosensitive chip set through colloid injection of a colloid mold, and a semi-spherical optical path is integrally packaged. According to the utility model, the problems of poor linearity and gain stability caused by the fact that the colloid shape and size of a photoelectric device cannot be completely unified in the prior art are solved; the linear photoelectric coupler has the technical effect of ensuring the characteristics of high linearity and stable gain of the linear photoelectric coupler. 本实用新型属于半导体器件的加工技术领域，尤其涉及一种光电耦合器半圆球型光通路结构，光敏芯片组中所有的光敏芯片表面和红外芯片表面通过胶体模具注胶封铸透明胶体，并形成半圆球型光通路整体封装，且整体封装下的光通路外形尺寸、高度及位置完全一致，本实用新型解决现有技术存在由于光电器件的胶体形状及大小尺寸无法完全统一，从而导致线性度和增益稳定性差的问题，具有确保线性光电耦合器的高线性和稳定增益的特性的
