Electro-optical module

An electro-optical module, comprising:

• a substrate having opposite first and second surfaces and a cavity penetrating the first and second surfaces;
• a heat sink having opposite top and bottom surfaces and disposed in the cavity in a manner that the bottom surface of the heat sink is exposed from the second surface of the substrate;
• a plurality of support members disposed on the first surface of the substrate;
• at least an electro-optical element having opposite active and non-active surfaces and disposed on the top surface of the heat sink via the non-active surface thereof;
• an interposer disposed on the first surface of the substrate and the electro-optical element for electrically connecting the electro-optical element to the substrate, wherein the interposer has a through hole corresponding in position to the active surface of the electro-optical element;
• and
• a transparent plate disposed over the first surface of the substrate and the interposer through the support members and having a lens portion corresponding in position to the through hole of the interposer.
