METHOD FOR PRODUCING AN INTEGRATED FINGERPRINT SENSOR, SENSOR CIRCUIT ARRANGEMENT, AND INJECTION ARRANGEMENT

摘要

The invention relates to, inter alia, a method for producing a fingerprint sensor comprising a dirt-repellent protective layer. In order to apply the protective layer, a starting material therefor is injected into a gap between a substrate of the sensor and a pressure plate, cf. method step (112). In this way, highly dirt-repellent protective layers can be structured without having recourse to photographic technology and abrasive processes.
