SEMICONDUCTOR DEVICE COMPRISING AN EMITTER OF RADIATION AND A PHOTOSENSOR AND APPERTAINING PRODUCTION METHOD |
| 摘要 |
The semiconductor device comprises a semiconductor substrate (1), a photosensor (2) integrated in the substrate (1) at a main surface (10), an emitter (12) of radiation mounted above the main surface (10), and a cover (6), which is at least partially transmissive for the radiation, arranged above the main surface (10). The cover (6) comprises a cavity (7), and the emitter (12) is arranged in the cavity (7). A radiation barrier (9) can be provided on a lateral surface of the cavity (7) to inhibit cross-talk between the emitter (12) and the photosensor (2). |
