  • Patent number: 11828636
    Abstract: In a flow rate sensor 10, a resistance bridge 100 detects a change in a gas flow rate. A differential A/D converter 122 converts an analog signal output from the resistance bridge 100 into a digital signal.

The disconnection detection unit 130 includes a detection capacitance 141 and a comparator 145. One connection portion of the detection capacitance 141 is connected to an input node of the A/D converter 122. The comparator 145 detects the disconnection of the bonding wires 164, 165 based on a potential based on a ratio of an electrostatic capacitance of a P-side input capacitance 116 or a N-side input capacitance 117 to an electrostatic capacitance of the detection capacitance 141. The P-side input capacitance 116 and the N-side input capacitance 117 respectively are connected to operation input units of the differential A/D converter 122.

  • Publication number: 20230215784
    Abstract: A preferred aim of the invention is to provide technique for improving reliability of semiconductor devices when using a low-dielectric-constant film having a lower dielectric constant than a silicon oxide film to a part of an interlayer insulating film. More specifically, to achieve the preferred aim, an interlayer insulating film IL1 forming a first fine layer is formed of a middle-Young's-modulus film, and thus it is possible to separate an integrated high-Young's-modulus layer (a semiconductor substrate 1S and a contact interlayer insulating film CIL) and an interlayer insulating film (a low-Young's-modulus film; a low-dielectric-constant film) IL2 forming a second fine layer not to let them directly contact with each other, and stress can be diverged. As a result, film exfoliation of the interlayer insulating film IL2 formed of a low-Young's-modulus film can be prevented and thus reliability of semiconductor devices can be improved.
