Abstract
A measuring device ( ) has a semiconductor arrangement, which includes a semiconductor chip ( ) connected to a carrier ( ) having at least one through-hole ( ). The semiconductor chip ( ) has at least one sensor ( ) with an active sensor surface ( ) facing the through-hole ( ). The semiconductor chip ( ) has electrical terminal points ( ), which are connected using flip-chip connections ( ) to terminal contacts ( ) facing the terminal points ( ) and located on the carrier ( ). The carrier ( ) has electrical strip conductors ( ), which connect the terminal contacts ( ) to contact elements ( ) located on the carrier. To the rear side of the carrier ( ) having the contact elements ( ) a strip conductor carrier ( ) is provided, which has strip conductors ( ) connected to opposing contacts ( ). The opposing contacts ( ) are each electrically connected using flip-chip connections ( ), to a contact element ( ), which are allocated to each of them. The semiconductor chip ( ) and the carrier ( ) enclose a measuring chamber. Between the carrier ( ) and the semiconductor chip ( ) a seal ( ) is arranged, which is constructed to be porous or semi-porous, at least in certain areas, or is constructed as a selectively permeable membrane, for bringing a substance into the measuring chamber.
