Patent attributes
An optoelectronic assembly includes an integrated circuit (IC) chip including, on its front side, a photoconversion region and first electrical contact pads disposed alongside the photoconversion region. A circuit substrate contains a cavity into which the IC chip is inserted through the lower side and has a window opening through the upper side in communication with the cavity such that the photoconversion region of the IC chip is exposed through the window. The circuit substrate includes electrical circuit traces, which include second electrical contact pads disposed within the cavity alongside the window so as to contact the first electrical contact pads on the front side of the IC chip within the cavity. A base includes a stiff, heat-conducting material, to which the lower side of the circuit substrate is fixed. A malleable heat-conducting layer is compressed between the rear side of the IC chip and the base.
