Gas detection device
First Claim
1. A gas detection device comprising:
- a substrate having a main surface; and
a movable film structure located on, and including a portion thereof spaced from, the main surface of the substrate, the portion of the movable film structure located over and spaced from the substrate including a first film formed of an insulating material, a patterned second film which deforms as a result of absorbing or adsorbing a predetermined gas, and a patterned third film comprising a resistive heater, at least a portion of the movable film structure spaced from the substrate being movable with respect to the substrate;
wherein from the perspective of a direction perpendicular to the main surface of the substrate, at least a portion of a pattern of the second film overlaps at least a portion of a pattern of the third film.

Abstract
A gas detection device includes a substrate having a main surface and a movable film structure located on, and including a portion thereof spaced from, the main surface of the substrate. The portion of the movable film structure located over and spaced from the substrate includes a first film formed of an insulating material, a patterned second film which deforms as a result of absorbing or adsorbing a predetermined gas, and a patterned third film comprising a resistive heater, at least a portion of the movable film structure spaced from the substrate being movable with respect to the substrate. From the perspective of a direction perpendicular to the main surface of the substrate, at least a portion of a pattern of the second film overlaps at least a portion of a pattern of the third film.
