Optical sensor arrangement and method of producing an optical sensor arrangement

摘要

An optical sensor arrangement, in particular an optical proximity sensor arrangement comprises a three-dimensional integrated circuit further comprising a first layer (1) comprising a light-emitting device (LED), a second layer (2) comprising a light-detector (PD) and a driver circuit (IC). The driver circuit is electrically connected to the light-emitting device (LED) and to the light-detector (PD) to control the operation of the light-emitting device (LED) and the light-detector (PD). A mold layer (3) comprising a first light-barrier (33) between the light-emitting device (LED) and the light-detector (PD) configured to block light from being transmitted directly from the light-emitting device (LED) to the light-detector (PD).
