Integrated circuit with sensor and method of manufacturing such an integrated circuit

A gas sensor on a semiconductor substrate. The gas sensor includes an elongate sensor element extending across an opening and has first and second opposed surfaces exposed for contact with a gas to be sensed. The first surface faces away from a major surface of the substrate. The second surface faces toward said major surface. The electrical conductivity of the elongate sensor element is sensitive to a composition and/or concentration of said gas to which the opposed first and second surfaces are exposable. The gas sensor further includes a support structure arranged to increase the mechanical robustness of the gas sensor by supporting the elongate sensor element in the opening.

Gas sensor

An electronic device (), the electronic device () comprising a substrate (), a convertible structure () arranged on and/or in the substrate (), being convertible between at least two states by heating and having different electrical properties in different ones of the at least two states, wherein the convertible structure () has a first portion having a first width (w), and has a second portion having a second width (w), the second width (w) being smaller than the first width (w), and a protrusion () protruding through the convertible structure () to thereby narrow the second portion of the convertible structure () from the first width (w) to the second width (w).

Integrated circuit and manufacturing method

The light dose received by perishable goods is an important parameter in determining the lifetime of those goods. A light sensor is described having a photosensitive element which changes its material property according to the light dose received. This change can be detected electrically by electrodes in the light sensor. Because the change in material property is permanent, this removes the need for a memory to store a value representing the light dose received by the light sensor.
