Abstract
The invention relates to a microchip assembly (40) that is particularly suited for biosensor applications in which a sensitive front side (13) of the associated microchip (10) has to be brought close to a sample. The microchip (10) comprises grooves or recesses on the front side of its substrate in which the connections to electrical tracks (42) are located. Thus the interconnection plane of the assembly is shifted backwards with respect to the sensitive front side (13) of the microchip (10), allowing a free access to the latter.
Claims10
A microchip (10), comprising
- a) a substrate (14);
- b) processing circuits (16) in a front side (13) of the substrate (14);
- c) at least one recess (12) in said front side (13) of the substrate (14) which has a depth (h) of more than 20 μm;
- d) at least one terminal pad for electrical connections of external lines to the processing circuits (16), the terminal pad being located in the recess (12).
