Method for manufacturing optoelectronic module

A method for manufacturing an optoelectronic module, comprising:

• providing a top cover with a reflective surface;
• forming a light-guiding structure;
• providing a mounting device;
• forming an optoelectronic device on said mounting device with a first precision;
• forming a control chip on said mounting device with a second precision different from said first precision;
• combining said top cover and said mounting device, wherein said light-guiding structure is between said top cover and said mounting device, and said optoelectronic device faces said reflective surface, wherein said mounting device has a concave structure, said mounting device comprises a substrate and a sub-mount, said concave structure is formed on said substrate, said control chip is mounted on said sub-mount with said second precision, and said optoelectronic device is mounted on a bottom surface of said concave structure of said substrate with said first precision;
• forming a through hole structure passing from said bottom surface of said concave structure to a bottom surface of said substrate;
• and
• bonding one end of at least one electrical trace on a top surface of said optoelectronic device and the other end of said electrical trace on said bottom surface of said concave structure to electrically connect with said through hole structure.
