Problems solved by technology

However, the current uncooled infrared sensing devices often have the problem that the light-absorbing area of ​​the sensing unit is too small, so that the infrared sensing device needs to use more sensing units in order to have a sensitive sensing capability.
On the other hand, in order to improve the thermal insulation effect of the sensing unit, the most common method at present is to design the structure of the bridge legs as a bent structure, however, this will easily lead to an overly cumbersome process

Abstract

A floating bridge structure comprises a substrate, a floating bridge layer and at least one bridge leg. The floating bridge layer is located on the substrate and is substantially parallel to the upper surface of the substrate. The bridge legs straightly extend from the substrate to the floating bridge layer. By means of the design, the effective light absorption area of the infrared sensing device can be increased, the overall sensing capacity of the infrared sensing device can be further improved, and the process convenience can be effectively improved.

Description

technical field [0001] The present application relates to a floating bridge structure and an infrared sensing device comprising the floating bridge structure. Background technique [0002] Generally speaking, the uncooled infrared sensing device can convert the infrared radiant heat emitted by the target into an electrical signal, so as to sense the target accordingly. However, the current uncooled infrared sensing device often has the problem that the light-absorbing area of ​​the sensing unit is too small, so that the infrared sensing device needs to use more sensing units in order to have a sensitive sensing capability. On the other hand, in order to improve the thermal insulation effect of the sensing unit, the most common method at present is to design the structure of the bridge leg as a bent structure, however, this will easily lead to a cumbersome process. Based on the above, how to increase the effective light-absorbing area of ​​a single sensing unit in an infrare...
