Infrared sensor

Detecting sensor

An infrared detector includes a circuit block carrying an infrared sensor element and electronic components. The circuit block is composed of a dielectric resin layer and a first substrate formed with a circuit pattern and mounting the electronic components. The dielectric resin layer is formed in its top with a recess which defines around its periphery with a shoulder for supporting opposite ends of the infrared sensor. The first substrate is integrated to the lower end of the dielectric resin layer with at least one of the electronic components being molded into the dielectric resin layer to make the circuit block of a unified mold structure. Thus, a part or all of the electronic components are molded into the dielectric layer to realize the circuit block of a simple and low profile structure, while retaining an advantage of keeping the infrared sensor element sufficiently away from the electronic components and an associated electronic circuit, thereby assuring to give the infrared detector which is simple in construction, economical in cost, and reliable in the infrared detection.

Infrared detector and process for fabricating the same

A pyroelectric-type IR receiving element comprises a pyroelectric substrate which is fixed to a supporting body at its support ends and at least one rectangular patch formed in the substrate. The patch is formed on its opposite surfaces with first and second electrodes which are overlapped to each other. The substrate has a U-shaped slit composed of a pair of side slits and a base slit connecting the side slits. The U-shaped slit surrounds continuously three sides of the patch, so that the patch is supported by the substrate in a cantilever fashion at a cantilever end which is opposed to one of the support ends of the substrate. Since a thermal stress applied to the substrate when the substrate is exposed to a temperature change is absorbed by the U-shaped slit, a stress concentration to be considered is not developed in the patch. As a result, it is possible to reduce the occurrence of popcorn noise, while maintaining good IR sensitivity.

An acceleration sensor element constitutes a piezoresistance type acceleration sensor in which an acceleration sensor chip including a cantilever structure of mass and beam parts and a piezoresistor formed on the beam part is mounted on a main lead which is slanted for positioning the piezoresistor and the center of gravity of the mass part substantially on the same horizontal plane in a mounted state of the sensor. The element thereby improves the reliability and assures such property as other-axis sensitivity of the sensor at the time of shipment.
