Abstract:
A measuring device (1) comprising at least one semiconductor arrangement including a semiconductor chip (2) and a carrier (4) connected thereto, the carrier having at least one through-hole (3) and the semiconductor chip (2) having at least one sensor (6) with an active sensor surface (5) facing the through-hole (3), the semiconductor chip (2) having electrical terminal points (9) connected by flip-chip connections (10) to terminal contacts (11) located on the carrier (4) and facing the terminal points (9), the carrier (4) having electrical strip conductors (12) which connect the terminal contacts (11) to contact elements (13) located on the carrier (4), and at least one strip conductor carrier (16) being provided with strip conductors (15) having opposing contacts (14) connected to the contact elements (13), at least a portion of the strip conductor carrier (16) being arranged on a rear side of the carrier (4) having the contact elements (13), with the opposing contacts (14) facing the contact elements (13) and being connected by flip-chip connections (17) to the contact elements (13) allocated to each of them, wherein the through-hole (3) and an area of the semiconductor chip (2) exposed by the through-hole (3) in the carrier (4) define a measuring chamber, and a seal (7) is arranged between the carrier (4) and the semiconductor chip (2), and wherein the seal (7) is constructed to be porous or semi-porous, at least in certain areas, for bringing a substance into the measuring chamber.
