Abstract

A gas sensor package includes a substrate, a gas sensing element on the substrate, and a cover module including ventilation holes and intended for covering the gas sensing element.

Description

technical field [0001] The present invention relates to gas sensor assemblies. Background technique [0002] There is a need for a gas sensor having features such as the speed at which a gas sensor can respond to its environment, the sensitivity to respond to the detection of a gas despite detecting a small amount of gas, the speed at which a gas sensor can The durability of how long it can run, the economic efficiency showing that the sensor can be used by the user without burden, etc. [0003] In order to integrate this gas sensor with existing semiconductor processing technology, the gas sensor should feature easy integration and counting. Household gas leakage alarms made of tin dioxide (SnO2) have been widely used as practical gas sensors. [0004] Gas sensors are classified into a semiconductor type that uses a change in resistance value according to a change in the amount of gas and an oscillator type that uses a change in oscillation frequency that occurs when gas ...
