Abstract
An integrated optical sensor comprises a semiconductor substrate (), an integrated circuit (), a dielectric layer (), a wiring (), a structured filter layer () and a diffuser (). The semiconductor substrate () has a main surface () and the integrated circuit () is arranged in the substrate () at or near the main surface (). Furthermore, the integrated circuit () comprises at least one light sensitive component (). The dielectric layer () comprises at least one compound of the semiconductor material. The dielectric layer () is arranged on or above the main surface (). The wiring () is arranged in the dielectric layer () and provides an electrical connection to the integrated circuit (), i.e. the wiring is connected to the integrated circuit (). The structured filter layer () is arranged on the dielectric layer () and faces the at least one light sensitive component (), i.e. the diffusor () is positioned over the structured filter layer (). In particular, the structured filter layer () is adapted for diffused incident light. The diffuser () is arranged on the structured filter layer ().
