Abstract: A calibration determination device includes: a free roll that conveys the bonding member; a load detection device that detects a load applied to a bearing of the free roll; a tension adjustment device that winds the bonding member to increase a tension applied to the bonding member and unwinds the bonding member to reduce the tension applied to the bonding member so as to adjust the tension applied to the bonding member; and a calibration determination unit that determines whether calibration of the load detection device is necessary. The tension adjustment device unwinds the bonding member to cause the bonding member not to be subjected to the tension, and the calibration determination unit determines whether the calibration of the load detection device is necessary based on the load detected by the load detection device with the bonding member not being subjected to the tension.

Abstract: A method for cleaning a receptor layer of a surface stress sensor according to an embodiment of the present invention includes, in a surface stress sensor that detects a change in surface stress of a thin film, the change being caused by a receptor layer disposed on a surface of the thin film, causing at least a part of a surface region of the thin film to generate heat or supplying heat to the receptor layer from the outside of the surface stress sensor. This makes it possible to easily perform efficient cleaning of a surface stress sensor such as a sensor that performs detection using a piezoresistor while avoiding structural complications as much as possible.

Abstract: An example microelectromechanical system (MEMS) force sensor is described herein. The MEMS force sensor can include a sensor die configured to receive an applied force. The sensor die can include a first substrate and a second substrate, where a cavity is formed in the first substrate, and where at least a portion of the second substrate defines a deformable membrane. The MEMS force sensor can also include an etch stop layer arranged between the first substrate and the second substrate, and a sensing element arranged on a surface of the second substrate. The sensing element can be configured to convert a strain on the surface of the membrane substrate to an analog electrical signal that is proportional to the strain.
