Patent ID: 6927465

Claim:
A compact sensing apparatus comprising: a signal conditioner semiconductor substrate; a sensor semiconductor substrate having a first surface thereof abuttingly connected to a first surface of the signal conditioner substrate; a signal conditioner circuit formed on a second surface of the signal conditioner semiconductor substrate for conditioning a sensing signal; and a sensor circuit formed on a second surface of the sensor semiconductor substrate and electrically connected to the signal conditioner circuit for generating the sensing signal in response to a predetermined physical stimulus, wherein the second surface of the sensor semiconductor substrate is orthogonal to the second surface of the signal conditioner semiconductor substrate, wherein the sensor circuit and the signal conditioner circuit are electrically connected via a conductive thermosetting material diffused into at least one recessed channel formed in the surface of the sensor substrate and into at least one channel formed in the surface of the signal conditioner substrate, the at least one recessed channel of the sensor substrate and the signal conditioner substrate being aligned to thereby provide a common channel bridging the sensor and the signal conditioner substrates for providing a conductive path between the sensor and the signal conditioner.
