Title: TRANSPONDER LAYER AND METHOD FOR PRODUCING SAME
Abstract:
The invention relates to a transponder layer (10), in particular for producing a chip card, comprising an antenna substrate (12), on an antenna side (11) of which an antenna (14) made of a wire conductor (13) is provided and which has a chip receiving area formed by a recess in the antenna substrate, wherein a chip (21) is received in said chip receiving area. Wire conductor ends which are used to form terminal ends (15) of the antenna are formed on a chip receiving area base (20) which is set back relative to the rear face (26) of the antenna substrate (12). The chip is received in the chip receiving area such that terminal contacts (22) arranged on a contact face (36) of the chip are contacted with flat contact areas (19) of the terminal ends (15), and the chip semiconductor body (28) rear face (27) which lies opposite the terminal contacts are substantially flush with the rear face of the antenna substrate. The invention further relates to a method for producing a transponder layer.
