摘要： Method and system for a wet/wet differential pressure sensor based on microelectronic packaging process. A top cap with a hole can be attached to a topside of a MEMS-configured pressure sense die with a pressure sensing diaphragm in order to allow sensed media to come in contact with the topside of the pressure sensing diaphragm. An optional constraint with a hole for stress relief can be attached to a backside of the pressure sense die. Adhesive and/or elastomeric seals and/or solder can be utilized to seal the pressure sense die allowing sensed media to come in contact with both sides of the pressure sensing diaphragm without coming into contact with wirebonds and other metallized surfaces. The MEMS-configured pressure sense die can also be bonded to a substrate with standard die attach materials. Such microelectronic packaging processes yield a high performance and cost effective solution thereby providing wet-wet pressure sensing capability.

摘要： The present disclosure relates to sensors including pressure sensors. In some cases, the pressure sensor may include a membrane or diaphragm, multiple sense elements connected to one another in a bridge configuration and positioned on the membrane, and an amplifier coupled to an output of the bridge configuration and having an output, where the diaphragm, sense elements and amplifier may be formed on a singled substrate or formed integrally therewith, or both. In one example, the pressure sensor may sense a particular range of pressures applied to the sensor, and/or may include an amplifier that has a selectable gain for amplifying an output of the bridge.

摘要： A pressure sensor system includes a pressure sensing capacitor and an inductor integrated in a substrate. The pressure sensing capacitor includes a conductive diaphragm for detecting a pressure differential and an electrode separated from the diaphragm by a predetermined gap formed in the substrate. The inductor and pressure sensing capacitor form a passive inductive-capacitive (LC) tank circuit. A remote interrogation circuit, inductively coupled to the pressure sensor inductor coil, can be utilized to detect changes in resonant frequency of the LC tank wirelessly. The fully integrated pressure sensor structure is manufactured utilizing layer-by-layer fabrication techniques.
