Abstract:
1. A method for manufacturing an integrated pressure sensor, comprising the steps of: providing a substrate with a first side and a second side, wherein the substrate includes conductive electrical traces located on the first and second sides; positioning a plurality of compensation circuits on the first side of the substrate in electrical contact with one or more of the conductive electrical traces on the first side of the substrate, wherein the compensation circuits are positioned in an array; positioning a plurality of pressure sensors on the second side of the substrate in electrical contact with one or more of the conductive electrical traces on the second side of the substrate, wherein each one of the sensors is associated with one of the compensation circuits to form a plurality of pressure sensor-compensation circuit pairs, and wherein the substrate includes conductive vias to electrically connect each of the sensor-compensation circuit pairs, where each of the compensation circuits provides temperature compensation for an associated one of the sensors; calibrating each of the sensor-compensation circuit pairs; and singulating each of the sensor-compensation circuit pairs for final packaging.
