摘要： A microelectromechanical system (MEMS) strain gauge pressure sensor includes a top wafer stack having a top surface and a first cavity that is configured to receive a first fluid at a first pressure, a backing wafer having a bottom surface opposite the top surface of the top wafer stack; a diaphragm wafer positioned between the top wafer stack and the backing wafer and having a second cavity that is configured to receive a second fluid at a second pressure, and a pedestal connected laterally to the top wafer stack, the backing wafer, and the diaphragm wafer. The diaphragm wafer includes a diaphragm extending between the first cavity and the second cavity, and a resistor positioned on the diaphragm. The MEMS strain gauge pressure sensor has a central axis such that the MEMS strain gauge pressure sensor has mechanical symmetries about the central axis.

摘要： In a pressure sensor having a configuration in which strain gauges are provided on a diaphragm, a change in sensor characteristic caused by a positional shift of the strain gauges is suppressed, and a change in sensor output in response to a change in temperature is suppressed. The pressure sensor is a pressure sensor obtained by arranging, on a diaphragm having a long side and a short side, a sensor chip in which four strain gauges having the same characteristic and constituting a bridge circuit are provided, the pressure sensor being for detecting, in the bridge circuit, voltage output that is in proportion to a pressure applied to the diaphragm, and the pressure sensor is configured as follows: the four strain gauges are arranged to be adjacent to one another in the vicinity of the center of the diaphragm so that two strain gauges are arranged along the short side and the other two strain gauges are arranged along the long side; and the diaphragm has a thin portion in a long-side direction seen from the sensor chip.
